NAME
int6kbaud - Qualcomm Atheros Serial Line Device Configuration
SYNOPSIS
int6kbaud [options] [...]
DESCRIPTION
Set serial line parameters on a UART-enabled Atheros powerline device using the ATBR
serial line command.
Serial line commands are 7-bit ASCII character strings sent to the local powerline device
over the host serial port. They can be sent using any terminal emulator but this program
will, in many cases, reduce typing and simplify scripting. It is especially useful for
downloading device parameters and uploading device parameters or firmware because those
operations involve large volumes of data. Also, this program permits decimal integer
arguments in many cases where the serial line commands require hexadecimal integer values.
See the COMMANDS section below for a list of supported serial line commands;
This program is part of the Qualcomm Atheros Powerline Toolkit. See the AMP man page for
an overview and installation instructions.
COMMENTS
This program does not configure or reconfigure host serial port settings since most
systems provide a utility to do that. Be sure to configure them before using this program
since other programs may change them before or after use. Atheros factory default
settings for UART-enabled powerline devices are 1115200 baud, 8 data bits, 1 stop bit, no
parity and no flow control.
On Linux, use the stty utility to inspect and set serial port parameters. The following
Linux command will configure serial device /dev/ttyS0 speed to 115200 baud with 8 data
bits, 1 stop bit, no parity bit and no flow control. Consult the stty man page for an
explanation of these and other options.
#stty -f /dev/ttyS0 115200 cs8 cstopb -cparenb -ixon
On Windows, use the the Device Manager dialog to set serial Port properties. To open this
dialog, select Start Menu, Control Panel, System, Hardware, Device Manager, Ports,
Advanced.
OPTIONS
-B baudrate
The new baud rate. Any integer value may be entered here but only certain values
may be accepted by the powerline device. Although the device may support some
value, the local host may not support it. Supported values are 300, 600, 1200,
2400, 4800, 9600, 38400, 57600, 115200, 230400, 460800 and 921600. The default is
115200.
-D databits
The number of bits per data byte. Accepted values are 7 and 8. The default is 8.
-F flowctrl
The hardware flowcontrol state. Accepted values are 0=off and 1=on where numeric
values or keywords "off" or "on" may be used. Keyword "none" is synonymous with
"off" for this option. The default is none.
-m mode
Accepted values are 1=transparent and 2=command where numeric values or keywords
"transparent" or "command" may be used.
-P parity
The number of parity bits and parity mode. Accepted values are 0=none, 1=odd and
2=even where numeric values of keywords "none", "odd" or "even" may be used. The
default is none.
-q Suppress progress and error information on stderr.
-s tty Communicate with the local powerline device over the named serial interface on the
local host. The program default is "/dev/ttyUSB0" for Linux and "com1:" for
Windows. The program default may be replace by defining environment variable
PLCUART. This command line option will over-ride those defaults.
-S stopbits
The number of stop bits. Accepted values are 1 or 2. The default is 1.
-u Force default host port settings to match the default setting for UART-enabled
Atheros powerline devices. The setting are 115200 baud, 8 data bits, no parity
bits and 1 stop bit. These settings will remain active when the program terminates
and will not change unless changed by some other means, perhaps by another
application. This option is an easy means of establishg an initial serial
connection with a powerline device, unless it's settings have been changed.
-v Display serial line commands and responses on stdout.
-w Place the local powerline device in Command Mode using the +++ serial line command.
The device will remain in command mode until it is reset or forced into
Transparaent Mode or High Speed Command Mode.
-?,--help
Print program help summary on stdout. This option takes precedence over other
options on the command line.
-!,--version
Print program version information on stdout. This option takes precedence over
other options on the command line. Use this option when sending screen dumps to
Atheros Technical Support so that they know exactly which version of the Linux
Toolkit you are using.
ARGUMENTS
None.
COMMANDS
This section lists serial line commands recognized by local powerline devices when in
Command Mode. Commands can be issued interactively using a terminal emulator, like minicom
on Linux or HyperTerminal on Windows or stored as text and copied to the serial port using
system utilities, like cat on Linux or type on Windows. This program merely converts
command line options and arguments into one or more of the serial line commands shown
below.
+++ Exit Transparent Mode and enter Command Mode. See option -w above.
AT Test for Command Mode by doing nothing, successfully. See option -t above.
ATBRmode,baudrate,databits,parity,stopbits,flowctrl
Set serial line parameters on the local powerline device. Beware that this will
break the existing serial connection when the new parameters differ from those of
the local host.
ATBSZ? Get Transparent Mode buffer size. See option -z above.
ATBSZsize
Set Transparent Mode buffer size. See option -Z above.
ATDST? Get Transparent Mode destination device address. See option -d above.
ATDSTaddress
Set Transparent Mode destination device address. See option -D above.
ATFD Reset local device to factory defaults. See option -T above.
ATHSC Exit Command Mode and enter High Speed Command Mode. Once the OK response is
received, the local host should send commands to the device at successively higher
speeds until a valid response is received.
ATNI? Read nework information and store the information internally. Return the number of
associated stations and information about the first associated station. The
information includes the peer station device address, TX rate and RX rate.
ATNIstation
Extract and display previously stored network information for a specific peer
station. The information returned is that previosly stored using a ATNI serial line
command query.
ATO Exit Command Mode and enter Transparent Mode. Successful switch requires a valid
destination MAC address, buffer size and aggregation timeout value. Use serial line
commands ATDST and ATBSZ to get and/or set the first two values. Use serial line
command ATTO to set the timeout value.
ATPStime
Place the device in Power Save Mode for a specified time in seconds. Accepted
values are 1 to 384 seconds. The default time is A seconds.
ATRPlength,offset
Read and display a parameter block segment where length is the number of bytes read
and offset is the relative position, in bytes, from the start of the parameter
block. Valid length values are 0 through 400 hexadecimal. See option -p above to
read and save an entire parameter block.
ATRPM Get PIB version and device MAC address.
ATRV Get hardware and firmware revision. See option -r above.
ATSK? Get device Network Membership Key. See option -m above.
ATSKkey
Set device Network Membership Key. See option -M above.
ATTO? Get the Transparent Mode aggregation timeout in milliseconds.
ATTOtimeout
Set the Transparent Mode aggregation timeout in milliseconds. See option -W above.
ATWNVmodule
Update NVM with PIB and/or Firmware module. See option -C above.
ATWPFmodule,length,offset,checksum,data
Write a parameter block or firmware segment to the local powerline device where
module is the module identifier, length is the number of bytes to write, offset is
the relative position from the start of the module, checksum is the 1's complement
of the data and data is the data to be written. Valid module identifiers are 1=FW
and 2=PIB. Valid length values are 0 up to 400 hexadecimal. See options -N and -P
above to write an entire parameter block or firmware images.
ATZ Reset device. See option -R above.

EXAMPLES
The following example sets the baud speed to 115200 baud with 8 data bits, 1 stop bits, no
flow control and no parity. The outgoing serial line command and incoming response are
displayed on stderr because option -f is present.
#int6kbaud -B 115200 -D 8 -F 0 -P 0 -S 1 -v
ATBR00,000000000001C200,08,00,01,00
OK
Observe that decimal command line arguments are converted to hexadecimal on output.
Although this program outputs fixed-length fields, including leaing zeros, device firmware
ignores them. Leading zeros may be omitted when entering serial line commands manually.
The next example set the speed to 38400. Observe that program default values appear in
the outgoing serial line command when the corresponding command line options are omitted.
#int6kbaud -B 38400 -v
ATBR00,0000000000009600,08,00,01,00
OK
The next command does the same thing as the first example except that keywords replace
numeric values for some of the options. Since option -v is omitted the outgoing command
and incoming response are not displayed.
#int6kbaud -B 115200 -D 8 -F off -P none -S 1
