Seyon - X11 Telecommunications Package.
seyon [-option ...] [-toolkit_option ...] [-- -emulator_option ...]
Seyon is a complete full-featured telecommunications package for the X
Window System. Some of its features are:
* Dialing directory that supports an unlimited number of
entries. The directory is fully mouse-driven and features call
progress monitoring, dial timeout, automatic redial, multi-
number dialing, and circular redial queue. Each item in the
dialing directory can be configured with its own baud rate, bit
mask, and script file. The dialing directory uses a plain-text
phone book that can be edited from withen Seyon. Seyon also
supports manual dialing.
* Terminal emulation window supporting DEC VT02, Tektronix 4014,
and ANSI. Seyon delegates its terminal emulation to xterm, so
all the familiar xterm functions such as the scroll-back buffer,
cut-and-paste utility, and visual bell are availabe through
Seyon’s terminal emulation window. Using xterm also means that
Seyon has a more complete emulation of VT102 than other any Unix
or DOS telecommunications program. Other terminal emulation
programs can also be used with Seyon to suit the user’s need;
for example, color xterm can be used to provide emulation for
color ANSI (popular on many BBS systems), and xvt can be used if
memory is a bit tight.
* Script language to automate tedious tasks such as logging into
remote hosts. Seyon’s script interpreter uses plain-text files
and has a syntax similar to that of sh, with a few extra
addtions. It supports many familiar statements such as
conditional branching by if-else and looping by goto. Scripts
may be assigned to items in the dialing directory for automatic
execution after a connection is made.
* Unlimited number of slots for external file transfer
protocols. Protocols are activated from a mouse-driven transfer
console that uses a plain-text file, editable from withen Seyon,
for protocol configuration. Seyon prompts the user for filenames
only if the chosen protocol requires filenames or if the
transfer operation is an upload, for which Seyon also accepts
wildcards. Multiple download directories can be specified for
the different transfer slots.
* Support for Zmodem auto-download. Seyon detects incoming
Zmodem signature and automatically activates a user-specified
zmodem protocol to receive incoming files. Zmodem transfers can
thus be completely automatic and require no user intervention.
* Translation modes. Seyon can perfrom useful trasnlations on
the user’s input. From example, Seyon can translate backspace to
delete (useful on may Unix systems), newline to carriage return
(useful on many BBS hosts), and my favorite, meta key
tranlation: to send keys pressed while the meta (ALT) key is
held down as an escape (ESC) followed by the key press. The
latter mode simulates the meta key on hosts that do not support
8-bit-clean connections and makes possible the use of the meta
key in programs like Emacs on such hosts.
* Other features: interactive setting of program parameters, on-
line help, software (XONN/XOFF) and hardware (RTS/CTS) flow
control, session capture to a file, and temporary running of a
local shell in the terminal emulation window.
Seyon is intended to be both simple and extensively configurable.
Almost every aspect of Seyon can be configured via the resources to
suit the user’s taste.
Besides the toolkit options, Seyon recognizes the following command-
Overrides the resource modems. Refer to the description of that
resource below. Unlike the resource, however, the list here has
to be quoted if it consists of more than one entry.
Instructs Seyon to use the specified program as the terminal
emulator. If Seyon fails to execute that program, it will fall
back to xterm. If this option is not given, Seyon will try to
use seyon-emu, which should be a link to your favorite terminal
emulation program. Seyon will fall back to xterm in this case as
well if it fails to execute seyon-emu.
-- This switch instructs Seyon to pass the rest of the command-line
to the terminal emulation program. All options following this
switch will be passed blindly to the emulator. This switch
cannot be combined with -noemulator.
Seyon usually invokes the terminal emulation program with some
options to set the application name and window and icon titles
(those are -name Seyon -T "Seyon Terminal Emulator" -n
Terminal). If this switch is given, Seyon will not pass those
options to the emulator. This is to accommodate terminal
emulation programs that use a different command-line syntax than
xterm -- like xvt, cmdtool, shelltool, ..etc. You can use the
’--’ switch to pass your own options to the emulator.
This option is valid only if Seyon is invoked from withen a
terminal emulation program in the foreground of an interactive
shell session. If given, Seyon will not launch a new terminal
emulator, but will use the existing one instead. You cannot use
the ’--’ switch if this option is given.
Causes Seyon to automatically executes the specified script
after the startup script is run. The specified script file will
be looked for according to the rule mentioned under the
description of the resource scriptDirectory below.
Overrides the resource defaultPhoneEntries. Refer to the
description of that resource below. Unlike the resource,
however, the list here has to be quoted if it consists of more
than one entry.
Overrides the resource dialAutoStart and sets it to ’on’ and If
both -dial and -nodial are specified on the command-line, the
override value will be set according to the last of the two on
Besides the toolkit resources, Seyon defines the following proprietry
Specifies whether Seyon is to look for Zmodem auto-download
signature. If enabled, Seyon will detect incoming Zmodem
signature and execute the action given by the resource
autoZmodemAction (typically to start a local rz). Otherwise,
Zmodem signature will be ignored. Default value: on
Specifies a simple or compound action that will be executed when
Zmodem auto-download signature is detected. This action will be
executed only if the resource autoZmodem is enabled (see above).
Refer to the section entitled SeQuickKeys for a description of
available actions. Default value: ShellCommand($rz);
Whether to translate user’s backspace to delete. When the remote
host is a Unix system, it’s better to set this to on, since many
Unix systems are not happy with backspace. Default value: off
The name of capture file. Seyon will write session captures to
this file when capture is enabled. This file will be placed in
Seyon’s default directory. The capture file will not be
overwritten by successive capture sessions. Seyon will merely
apped new capture to its end. Default value: capture
The modem connect string. This the string response the modem
gives when a connection is made after dialing. Default value:
The default number of bits (character size). Seyon will set the
number of bits to this value on startup and will use it for
items in the dialing directory for which no such parameter is
given. Valid values are 5, 6, 7, and 8. Default value: 8
The default baud rate. Seyon will set the baud rate to this
value on startup and will use it for items in the dialing
directory for which no baud rate is given. Default value: 9600
Seyon’s default directory. When looking for its files, Seyon
will first try this default directory, then the current
directory. Seyon will also put the capture file in this
directory. Default value: ~/.seyon
The default parity. Seyon will set the parity to this value on
startup and will use it for items in the dialing directory for
which no such parameter is given. Valid values are 0 (no
parity), 1 (odd parity), and 2 (even parity). Default value: 0
defaultPhoneEntries (int array)
This resource specifies a list of numbers corresponding to the
order the entries in the dialing directory appear at. Seyon will
highlight (select) those entries on startup and whenever you
click ‘‘Default’’ from the dialing directory. This is useful if
there is a set of entries that you most frequesntly dial that
want to be highlghted automatically instead of doing that every
time by hand. You can override this resource by the -entries
command-line switch. Unlike the command-line switch, however,
the list here should not be quoted. Phonebook entries numbering
starts at one. No default value.
The default number of stop bits. Seyon will set the number of
stop bits to this value on startup and will use it for items in
the dialing directory for which no such parameter is given.
Valid values are 1 and 2. Default value: 1
This resource specifies that Seyon should start dialing the
entries specified by the resource defaultPhoneEntries (or its
override command-line switch) on startup. Seyon will commence
dialing those entries after executing the startup script and any
script specified at the command line. A more convenient way of
automatic dialing on startup is to use the override command-line
switch -dial, which overrides this resource and enables. If the
resource is enabled, it can be disabled at the command line by
the override switch -nodial. Refer to the description of these
switches above. Default value: off
The string Seyon sends to the modem to cancel dialing while in
progress. Default value: ^M
How long in seconds Seyon should wait after no connection is
made withen dialTimeOut before ciculating to the next number.
Default value: 10
This is a format string that specifies the layout of the dialing
direcotry. The default is ’%-15s %-15s %6s %1c%1c%1c %1c%1c %s’
(no quotes). Briefly: the fields represent the host name,
number, the baud rate, bits, parity, stop bits, whether there is
a custom prefix, suffix, and the script name. You can understand
more what each field refers to by comparing with dialing
directory, fields that use the current setting (via the keyword
CURRENT) are designated by a question mark. Notice that you
cannot change the order the items in the dialing directory
appear at, only the format. For example, if the numbers you call
are all 7-digits, your host names are short, you never use baud
rates above 9600, and you like dashes between the baud rate,
bits, parity, and stop bits fields, then you may prefer to use
the format string ’%-10s %-8s %5s-%1c-%1c-%1c %1c%1c %s’, which
would be narrower than the default format. Default value: %-15s
%-15s %6s %1c%1c%1c %1c%1c %s
The string Seyon sends to the modem before the phone number. To
use pulse dialing, set this resource to .IR ATDP . Default
How many times Seyon should try dialing a number. Seyon will
give up on dialing a number if no connection is made after this
many tries. Default value: 5
The string Seyon sends to the modem after the phone number. This
string has to contain a carraige return or the number will never
get sent to the mode. Default value: ^M
How long in seconds Seyon should wait for a connection to made
after dialing is complete. Seyon will cancel the dialing if no
connection is made withen this period. Default value: 45
Whether Seyon should prompt for hanguping up before exiting. If
off-line and the resource ignoreModemDCD is set to ’off’, Seyon
will not prompt for hanging up upon exiting even if this
resource is set to Default value: on
funMessages (string array)
The fun messages to be displayed when Seyon has no other
important information to show. This should be a list of double-
quoted [funny] sentences. Default value: varies, version-
The temporal interval in seconds between successive fun
messages. Default value: 15
If set to on, Seyon will send a string to the remote host
whenever the terminal session is idle (no keyboard input) for a
given amount of time. The resources idleGuardInterval and
idleGuardString specify the above time interval and the string
to be sent to the remote host when idle. It is useful to enable
this features to keep the session alive when one is away from
the computer for a while (e.g. to prevent auto-logout).
Default value: off
The amount of time in seconds Seyon is to consider the session
idle when there is no keyboard activity at the terminal for that
long. Seyon will send a string to the remote host every such
interval as long as the session is idle. Default value: 300
The string to be sent to the remote host when the session is
idle. This string will be sent at a regular interval as long as
the sesiion remains idle. Note that the current translations
will be used in sending this string; for example, if
backspaceTranslation is enabled, then the default string
<Space><BS> will be sent as <Space><DEL>. Default value: \s^H
(space then backspace)
If this resource is set to ’on’, the modem DCD (Data Carrier
Detect) status will be ignored. Some of the consequences of
setting this to ´on´ is that Seyon will always prompt for hangup
(if the resource exitConfirm is set to ’on’) even if the modem
DCD status indicates that it is off-line, and dialing will be
attempted even if the modem DCD status indicates that it is on-
line. It is highly recommended that you keep this set to ’off’
unless your modem does not honor the DCD line. Consult your
modem’s manual for more details. Default value: off
When set to on, Seyon will hangup the line (if connected) before
dialing the phone number. Otherwise, the number will be dialed
without hanging up, and it is the user’s responsibility to
ensure that the line is clear (no connection) when dialing.
Default value: on
Whether Seyon should ask for confirmation before hanging up the
phone Default value: on
When enabled, Seyon will hangup up the modem by dropping DTR.
This is much quicker than hanging up by sending a Hayes-like
hangup string to the modem and waiting to allow for escape guard
time. However, some modems and serial drivers choke on dropping
DTR and others just don’t hangup when DTR is dropped, so in
these cases it should be disabled. If disabled, Seyon will
hangup the modem by sending the string specified by the resource
modemAttentionString, followed by that specified by the resource
modemHangupString. Default value: off
Whether to transmit keys pressed while the meta (ALT) key is
held down as an escape (ESC) followed by the key press. Most
hosts do not support 8-bit sessions, and hence do not recognize
the meta key. Therefore, this translation mode has to be
enabled when connected to such hosts to take advantage of the
meta key in programs that make use of it like Emacs. Default
The string to send to the modem to get its attention (switch to
command mode). This string will be sent to the modem before the
hangup string when hangupViaDTR is disabled. Default value: +++
The hangup string to send to the modem when hangupViaDTR is
disabled. Default value: ATH^M
A list of modem devies to use. Seyon will try modems in this
list one after the other until it finds an available modem or
the list is exhausted. No default value.
This resource controls the amount of time (in seconds) between
updates to the modem status toggles (including the clock). The
default is five seconds, but you can set it to one second (or
any other number) if you want the toggles to be updated more
frequently. Even if you set this to a large number, Seyon is
intellegent enough to update the toggles after each connect or
hangup. Default value: 5
This resource specifies the minimum number of characters that
should be in the buffer before the read process is satified. The
read process will wait until that number of incoming characters
is in the buffer or 0.1 second has elapsed between the
receiption of two characters before displaying the data in the
buffer. This results in the data being displayed in chunks and
speeds up the terminal display. The speedup would be most
noticeable on slow machnes with fast modems.
Leave this resource at its default (1) or set it at a low value
(6) if you have a slow modem (e.g. 2400bps). Otherwise you might
set it to the maximum value, which is platform-dependent but
generally 255. If you set it to any number greater than the
maximum value, it will be truncated to the maximum value.
Default value: 1
When the Enter key is pressed, newline character (\n) is
generated. This resource determines what to translate this
character to. Three modes are possible: no translation
(newline), carriage return (\r), and carriage return / line
feed. Unix systems usually expect newline or carrage return, DOS
systems expect carraige return or carriage return / line feed.
The three keywords corresponding to the above modes are nl, cr,
and cr/lf. Default value: cr
noConnectStringX [X = 1-4] (string)
The response strings given by the modem when connection fails.
Default values: NO CARRIER, NO DIALTONE, BUSY, VOICE
The name of the phone list (dialing directory) file. See the
included example to learn how this file should be formatted.
Default value: phonelist
Specifies a simple or compound action that will be executed
after a connection to a remote host is made. This action will be
executed before running any script attached to that host in the
dialing directory. All actions here have to be synchronous.
Refer to the section entitled SeQuickKeys below for a
description of available actions. Default value: Beep();
The name of the protocols file. This file tells Seyon what file
transfer protocols are available. The user will be promted with
a list based on this file when file transfer is to be initiated.
Default value: protocols
Refer to the section entitled SeQuickKeys below.
Whether Seyon should turn on RTS/CTS hardware flow control. Make
sure the modem is set to use this as well. Default value: off
Seyon’s script directory. When looking for scripts, Seyon will
first try this script directory, then the current directory.
Default value: defaultDirectory
Whether to display funny messages when Seyon has no other
important information to show. Seyon will display those messages
at an interval specified by the funMessagesInterval resource
when there is no other important information to convey to the
user. To disable the display of fun messages, this resource has
be set to off. Default value: on
Specifies a simple or compound action that will be executed on
startup. This action is executed prior to running any script (in
case the -script switch is given) or dialing any entry of the
dialing directory (in case the -dial switch is given or the
resource dialAutoStart is enabled). You can make Seyon open the
dialing directory automatically on startup by using the simple
action ‘‘OpenWidnow(Dial);’’ as a constituent of this complex
action stack. Note that running the startup script is just a
special case of this resource. Refer to the section entitled
SeQuickKeys for a description of available actions. Default
Seyon’s startup file. Seyon will execute all commands in this
file upon startup. This file can have any commands acceptable as
script commands. The most useful command to put here is the set
command, to set the various communications parameters. Default
Whether to strip the high (eights) bit from incoming characters.
If set to on, the high bit of all incoming characters will be
stripped, which will make an 8-N-1 setting behave like 7-N-1,
even though eight bits are used for each character. Default
Whether Seyon should turn on XON/XOFF software flow control.
Default value: off
Seyon allows the user to have custom buttons, called SeQuickKeys (z
quickies), to which actions can be attached. SeQuickKeys provide a
convenient way via which the user can invoke frequently-used operations
by a singe mouse click. SeQuickKeys are specified through the resources
quickKeyX, where X is an integer corresponding to the order at which
that SeQuickKey is to appear on the command center. Relevant subparts
of that resource are visible, action, and label. Here is an example:
Seyon*quickKey3.action: FileTransfer(1,file); Beep();
The first line specifies that SeQuickKey3 should be visible. The second
line specifies the action bound to the SeQuickKey (in this case, a
compound action), and the third line specifies the label for that
SeQuickKey’s button. Other subparts can also be specified in a similar
fashion (e.g. background, foreground, ..etc.)
Actions can be either simple or compound. A compound action consists of
a stack of simple actions and can be used as simple mini-script.
· Set(idleGuard,on); DialEntries(Default);
· Echo("Uploading files..."); Transmit(rz); \
FieTransfer(1,"*.ico $HOME/acct.wks"); Echo(Done);
· OpenWindow(Dial); DialEntries("2 5 6");
· Echo("Goodbye.."); Hangup(); Quit();
· Set(baud,9600); ManualDial("555-5555");
· Echo("Will upload..."); ShellCommand("$sz *.wks");
· Set(parity,0); RunScript(login.scr); Echo(Finished);
The following is a list of actions Seyon currently supports. Asterisks
designate asynchronoous actions. Brackets designate optional arguments.
Rings the bell making a short beep.
Closes (dismisses) the given windows. Currenly the only valid
argument to this action is Dial, which corresponds to the
dialing idrectory window. Example: CloseWindow(Dial);
Dials entries in the dialing directory corresponding by order to
the given list. Entries will be dialed as if the user had
selected them on the dialing directory. Entries will be dialed
without opening the dialing directory. You can use the action
‘‘OpenWindow(Dial);’’ and stack the two actions in a compound
action if you want the dialing directory to be opened.
The list must be quoted if it consists of more than one entry,
and entries should be separated by white space, not commas. If
the list consists of just the word ‘‘Default’’, then the entries
given by the resource defaultPhoneEntries will be dialed, refer
to the description of that resource for more details.
The most common use of this action is attach frequesntly-dialed
hosts to SeQuickKeys, making dialing those hosts a one-click
operation. If this action is not the last in a compound action
stack, actions specified by the resource postConnectAction may
not work properly. Examples: DialEntries(2); DialEntries("2 4
Sends the given file to the remote host as a text upload. If the
optional argument ‘‘file’’ is not specified, Seyon will pop up a
dialog box asking for the file name. In the latter case this
action is similar to clicking Divert from the Misc window.
Examples: DivertFile("/tmp/acct.wks"); DivertFile();
Echos the given string to the terminal. Does not send it to the
modem (use Transmit for that). If the string consists of more
than one word, it must be quoted. Note that unlike the shell
command of the same name, this command does not accepts the
switch -n but always appends newline to the string. If the
argument is omitted, an empty line will be echoed. Examples:
Echo(Hello); Echo("Hello there"); Echo();
Executes the transfer protocol corresponding by order in the
trasfer console (protocols file) to ‘‘entry’’. If that protocol
requires a file name and file-list is omitted, Seyon will pop up
a dialog box asking for the file. Otherwise file-list will be
passed to that protocol. The list must be quotes if it consists
of more than one word and items in it should be separated by
white space. It can contain wild cards and shell variables.
Examples: FileTransfer(1); FileTransfer(2,acct.wks);
Disconnects the line. Does not pop up a confirmation box.
Iconifies the given windows. Valid arguments to this action are
Main, Dial, and Term, corresponding respectively to the command
center, dialing directory, and terminal emulator windows. When
the argument is Term, this action will work only if the terminal
emulator sets the envirenment variable WINDOWID, like xterm
does. Examples: IconifyWindow(Main,Dial,Term);
Dials a number as if the Manual button had been clicked from the
dialing directory. If ‘‘number’’ is specified, it will be dialed
directly and no dialog box will be popped up asking for the
number. Examples: ManualDial(555-5555); ManualDial();
Echos the given string to the message box of Seyon’s command
center (main window). If the string consists of more than one
word, it must be quoted. If the argument is omitted, an empty
line will be echoed. Examples: Message(Hello); Message("Hello
Opens each of the given windows by popping it if closed or de-
iconifying it if in an iconic state. Valid arguments to this
action are Main, Dial, and Term, corresponding respectively to
the command center, dialing directory, and terminal emulator
windows. When the argument is Term, this action will work only
if the terminal emulator sets the envirenment variable WINDOWID,
like xterm does. Examples: OpenWindow(Main,Dial,Term);
Exits Seyon completely and returns to the shell. Does not pop up
a confirmation box.
Executes the script given by the file script-name. The script
will be executed as if the user had selected it via the Script
button. If script-name is omitted, a dialog box will be popped
up asking for the script name. This is a very versatile action,
as many remote and local commands or series of commands can be
performed by attaching appropriate scripts to SeQuickKeys.
Examples: RunScript(login.scr); RunScript();
Sets the specified parameter to the given value. Can be used to
set the various communications parameters. Available parameters
are listed under the script command ‘‘set’’. Examples:
Set(baud,9600); Set(parity,0); Set(idleGuard,off).
Executes the given shell command via the user’s shell pointed to
by the SHELL environment variable, or /bin/sh if that
environment variable is not set. Note that the command must be
quoted if it consists of more than one word. If the first non-
space letter of the command is the character ‘‘$’’, then
standard input and standard output will be redirected to to the
modem. This action can be used to execute any external program
from withen Seyon. Example: ShellCommand(ls); ShellCommand("$cd
$HOME; sz -vv *.wks");
Transmits the given string to the remote host. The string must
be quoted if it consists of more than one word. The string is
transmitted as is (no case conversions are performed). No
newline character or carriage return is appended to the string,
use the prefix characters for that (e.g. ^M, ^J). See the
discripttion of the script command ‘‘transmit’’ for more
details. Example: Transmit(ls^M); Transmit("ls -CF^M");
Script files can automate some tedious tasks such as logging into a
system. A script file is an ascii text file and may be entered or
edited using any standard text editor.
The script file is read line by line. Empty lines (consisting of white
space only) are ignored. Comments are lines whose first non-space
character is a pound sign (#).
The script processor reads each script line, ignoring leading white
space, into words. A word is defined as either:
· a sequence of characters delimited by white space, or
· a sequence of characters enclosed in single or double quotes.
The first word of a script file is considered the command word. If the
last character of the command word is a colon (:), the line is
considered to be a label (the object of a goto statement). Otherwise,
it is assumed to be a script command and is interpreted as such.
Command words are case insensative.
Some commands take one or more arguments. Each argument is parsed as a
single word as defined above. If blanks are required in an argument,
the argument must be quoted using single or double quotes.
Script Command List
Below is the description of all commands that may be used in the Seyon
capture on|off (currently may not work)
The command capture on will enable capture. All characters
received during waitfor processing will be appended to the
capture file. The command capture off will close the capture
file. This setting does not currently extend to terminal mode.
This may be offered in a later release.
If the argument is on, all subsequent command lines processed
will be displayed on the local screen. The exception to this is
lines containing a transmit command. These lines will just print
TRANSMIT..., so that passwords, etc. can be protected. If the
argument is off, scripts will execute quietly (this is the
Dial the specified number. Seyon supports generic "Hayes"
compatible modems for dialing. Note that this command requires
an actual phone number. The phonebook is not used for this
Echos the given string to the terminal. Does not send it to the
modem (use transmit for that). If the string contains spaces, it
must be quoted. Note that unlike the shell command of the same
name, this command does not accepts the switch -n but always
appends newline to the string.
exit Terminates the script file prior to the end of file. Returns to
flush Flushes the modem, i.e. discards data written to the modem but
not transmitted and data received but not read.
Goes to the specified label in the script file and continues
execution from that point. The label may either precede or
follow the actual goto statement. A label is any command word
whose last character is a colon (:).
hanup Hangups up the line and disconnects from the remote host.
if, else, endif
Conditionally executes statements based on specified condition.
Seyon supports the following conditions:
waitfor: true if the last waitfor command was successful.
linked: true if this script was executed from the dialing
Conditions may be negated using the prefix not or the character
!waitfor: true If the last waitfor command timed out.
not waitfor: same as !waitfor above
The else and endif keywords must appear on their own lines. If
statements may not be nested.
Suspends execution of the script for the specified number of
seconds. This is usually used for timing considerations; for
example, waiting a couple of seconds after receiving the connect
message and typing ^C to CompuServe.
purge Reads and discards all data coming from the modem for the
duration of one second.
quit Terminates the script and exits the whole program (returns to
redial Redials the last number dialed using the dial command.
Sends a BREAK signal to te remote host.
set <parameter> <value>
Sets the specified parameter to the given value. Can be used to
set the various communications parameters for each host. The
follwoing is a list of the set keywords that Seyon recognizes.
Keywords marked with an asterisk set the current parameter only,
not the default one. Refer to the corresponig resource (in
parentheses below) for details of the function of each keyword.
Boolean keywords accept on or off as their argument, other
keywords accept the same arguments as the corresponding
Executes the given shell command via the user’s shell pointed to
by the SHELL environment variable, or /bin/sh if the environment
variable SHELL is not set. Note that the command must be quoted
if it consists of more than one word. If the first non-space
letter of the command is the character ’$’, then standard input
and standard output will be redirected to to the modem. This
command can be used to execute any external program from withen
Seyon. Example: shell "cd /usr/dl; rz -vv".
Transmits the specified text to the remote host. The text
argument should be quoted (using single or double quotes) if
there are spaces to be transmitted. The text is transmitted as
is (no case conversions are performed).
^ is the Control character prefix: the next character is made
into a control character. For example, ^M is carriage return
(0x0D) and ^J is newline (0x0A).
\ is quote prefix: the next character is transmitted verbatim.
For example, \^ would transmit a literal ^.
This command specifies whether or not characters received from
the modem will be displayed on the local terminal. Since the
only time that the script processor looks at the receive queue
is during waitfor processing, the displays may look a bit
erratic. Use the tty off command to disable local display of
received characters during script processing.
waitfor <text> [timeout]
Waits for the specified text to appear from the modem. The text
argument should be quoted (using single or double quotes) if
there are spaces to be transmitted.
Special characters are interpreted the same as for transmit. If
the timeout argument is specified, Seyon will wait that number
of seconds for the string to appear. If no timeout is given,
Seyon defaults to 30 seconds.
During waitfor processing, characters received (up to and
including the last character found in the text or in the

specified), and/or displayed to the screen (if tty on is
when [<string-to-expect> <string-to-send>]
Sends string-to-send whenever it encounters string-to-expect
while waiting in a waitfor command, whatever the number if times
string-to-expect is encountered.
This is is useful if the order of prompts expected is not known
before hand. For example, some BBS systems (notably PCBoard)
change the prompts depeding on the time of call, and a complete
script for such boards cannot be written using waitfor only.
As many number of when commands as desired can be specified. A
when command with no arguments clears all outstanding when
commands. waitfor commands take precedence over when commands
if they expect the same string.
A typical use of this command would be:
when "Continue?" "y^M"
when "More?" "n^M"
waitfor "BBS Command?"
The above script keeps sending "y^M" to every Continue?" prompt
and "n^M" to every "More?" prompt until the the string "BBS
Command?" is encountered. The lasy when clears all outstanding
The default Seyon files are startup, phonelist, and protocols. These
have to be in the current directory, Seyon’s default directory
(~/.seyon), or the user’s home directory. The default script directory
is Seyon’s default directory. All of these files and directories can be
overridden by setting the appropriate resources. See the description of
those resources as well as the description of the files above.

If Seyon is hung, it can be made to exit cleanly by killing its main
process by signal 15 (SIGTERM) from another shell. Seyon’s main process
is the one that has the lowest PID (Process ID) number. For example, if
1100 p0 S 0:04 seyon -noemulator
1101 p0 S 0:00 seyon -noemulator
1102 p0 S 0:38 seyon -noemulator
Then ‘‘kill -15 1100’’ or ‘‘kill 1100’’ would cause Seyon clean up and
