NAME

       rotctl - control antenna rotators

SYNOPSIS

       rotctl [OPTION]... [COMMAND]...

DESCRIPTION

       Control  antenna  rotators.  rotctl accepts commands from the command line as well as in interactive mode
       if none are provided on the command line.

       Keep in mind that Hamlib is BETA level software. While a lot  of  backend  libraries  lack  complete  rig
       support,  the  basic functions are usually well supported.  The API may change without publicized notice,
       while an advancement of the minor version (e.g. 1.1.x to 1.2.x) indicates such a change.

       Please report bugs and provide feedback at the e-mail  address  given  in  the  REPORTING  BUGS  section.
       Patches and code enhancements are also welcome.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').

       Here is s summary of the supported options:

       -m, --model=id
              Select rotator model number. See model list (use 'rotctl -l').

              NB:  rotctl  (or  third party software) will use rig model 1901 when using rpc.rotd or rig model 2
              for NET rotctl (rotctld).

       -r, --rot-file=device
              Use device as the file name of the port the rotator is connected.  Often a serial port, but  could
              be  a  USB  to serial adapter or USB port device.  Typically /dev/ttyS0, /dev/ttyS1, /dev/ttyUSB0,
              etc. on Linux or COM1, COM2, etc. on Win32.

              Also used to specify the host and port to connect to a listening rotctld daemon on POSIX:

              -r localhost:4533

              and on Win32:

              -r 127.0.0.1:4533

       -s, --serial-speed=baud
              Set serial speed to baud rate. Uses maximum serial speed  from  rotator  backend  capabilities  as
              default.

       -t, --send-cmd-term=char
              Change  the  termination char for text protocol when using the send_cmd command. The default value
              is <CR>. Non ASCII printable characters can be  specified  as  an  ASCII  number,  in  hexadecimal
              format,  prepended  with  0x.  You may pass an empty string for no termination char. The string -1
              tells rotctl to switch to binary protocol.  See the send_cmd command for further explanation.

       -L, --show-conf
              List all config parameters for the rotor defined with -m above.

       -C, --set-conf=parm=val[,parm=val]*
              Set config parameter.  e.g. --set_conf=stop_bits=2

              Use -L option for a list.

       -u, --dump-caps
              Dump capabilities for the rotor defined with -m above and exit.

       -l, --list
              List all model numbers defined in Hamlib and exit.  As of 1.2.15.1 the list  is  sorted  by  model
              number.

              N.B.  In  Linux  the  list  can  be scrolled back using Shift-PageUp/ Shift-PageDown, or using the
              scrollbars of a virtual terminal in X or the cmd window in Windows.  The output can  be  piped  to
              'more' or 'less', e.g. 'rotctl -l | more'.

       -v, --verbose
              Set verbose mode, cumulative (see DIAGNOSTICS below).

       -h, --help
              Show summary of these options and exit.

       -V, --version
              Show version of rotctl and exit.

       N.B.  Some  options  may  not  be  implemented by a given backend and will return an error.  This is most
       likely to occur with the --set-conf and --show-conf options.

       Please note that the backend for the rotator to be controlled, or the rotator itself may not support some
       commands. In that case, the operation will fail with a Hamlib error code.

COMMANDS

       Commands can be entered either as a single char, or as a long command name.  Basically, the  commands  do
       not  take  a  dash  in front of them, as the options do. They may be typed in when in interactive mode or
       provided as argument(s) in command line interface mode.

       Since most of the Hamlib operations have a set and a get method, an upper case letter will  be  used  for
       set  method whereas the corresponding lower case letter refers to the get method. Each operation also has
       a long name; in interactive mode, prepend a backslash to enter a long command name.

       Example: Use "\get_info" to see the rotor's info.

       Please note that the backend for the rotator to be controlled, or the rotator itself may not support some
       commands. In that case, the operation will fail with a Hamlib error message.

       A summary of commands is included below (In the case of "set" commands the quoted string is  replaced  by
       the  value  in  the  description.  In the case of "get" commands the quoted string is the key name of the
       value returned.):

       Q|q, exit rotctl
              Exit rotctl in interactive mode.

              When rotctl is controlling the rotor directly, will close the rotor backend and port.  When rotctl
              is connected to rotctld (rotor model 2), the TCP/IP connection to rotctld is  closed  and  rotctld
              remains running, available for another TCP/IP network connection.

       P, set_pos 'Azimuth' 'Elevation'
              Set position: Azimuth and Elevation as double precision floating point values.

       p, get_pos
              Get position: 'Azimuth' and 'Elevation' as double precision floating point values.

       M, move 'Direction' 'Speed'
              Move the rotator in a specific direction at the given rate.

              Values  are  integers  where  Direction  is defined as 2 = Up, 4 = Down, 8 = Left, and 16 = Right.
              Speed is an integer between 1 and 100.  Not all backends that implement the move command  use  the
              Speed value.  At this time only the gs232a utilizes the Speed parameter.

       S, stop
              Stop the rotator.

       K, park
              Park the antenna.

       C, set_conf 'Token' 'Value'
              Set  a configuration parameter.  It is safe to give "Token" a value of '0' (zero).  "Value" may be
              a string up to 20 characters.
              See -L output

       R, reset 'Reset'
              Reset the rotator.

              Integer value of '1' for Reset All.

       _, get_info
              Get misc information on the rotator.

              At the moment returns 'Model Name'.

       w, send_cmd 'Cmd'
              Send raw command string to the rotator.
              <CR> (or send-cmd-term, see -t option) is appended automatically at the end  of  the  command  for
              text protocols.  For binary protocols, enter values as \0xAA\0xBB

       Locator Commands

       These  commands  offer conversions of Degrees Minutes Seconds to other formats, Maidenhead square locator
       conversions and distance and azimuth conversions.

       L, lonlat2loc 'Longitude' 'Latitude' 'Loc Len [2-12]'
              Returns the Maidenhead locator for the given 'Longitude' and 'Latitude'.

              Both are floating point values.  The precision of the returned square is controlled by  'Loc  Len'
              which should be an even numbered integer value between 2 and 12.

              For example, "+L -170.000000 -85.000000 12\n" returns "Locator: AA55AA00AA00\n".

       l, loc2lonlat 'Locator'
              Returns  'Longitude'  and 'Latitude' in decimal degrees at the approximate center of the requested
              grid square (despite the use  of  double  precision  variables  internally,  some  rounding  error
              occurs).   West  longitude  is  expressed  as  a negative value.  South latitude is expressed as a
              negative value.  Locator can be from 2 to 12 characters in length.

              For example, "+l AA55AA00AA00\n" returns "Longitude: -169.999983\nLatitude: -84.999991\n".

       D, dms2dec 'Degrees' 'Minutes' 'Seconds' 'S/W'
              Returns 'Dec Degrees', a signed floating point value.

              Degrees and Minutes are integer values and Seconds is a floating point value.  S/W is a flag  with
              '1'  indicating  South  latitude  or  West  longitude and '0' North or East (the flag is needed as
              computers don't recognize a signed zero even though only  the  Degrees  value  only  is  typically
              signed in DMS notation).

       d, dec2dms 'Dec Degrees'
              Returns 'Degrees' 'Minutes' 'Seconds' 'S/W'.

              Values are as in dms2dec above.

       E, dmmm2dec 'Degrees' 'Dec Minutes' 'S/W'
              Returns 'Dec Degrees', a signed floating point value.

              Degrees  is  an  integer  value  and  Minutes  is  a floating point value.  S/W is a flag with '1'
              indicating South latitude or West longitude and '0' North or East (the flag is needed as computers
              don't recognize a signed zero even though only the Degrees value only is typically signed  in  DMS
              notation).

       e, dec2dmmm 'Dec Deg'
              Returns 'Degrees' 'Minutes' 'S/W'.

              Values are as in dmmm2dec above.

       B, qrb 'Lon 1' 'Lat 1' 'Lon 2' 'Lat 2'
              Returns 'Distance' 'Azimuth' where Distance is in km and Azimuth is in degrees.

              All Lon/Lat values are signed floating point numbers.

       A, a_sp2a_lp 'Short Path Deg'
              Returns 'Long Path Deg' or -RIG_EINVAL upon input error..

              Both are floating point values within the range 0.00 to 360.00.

       a, d_sp2d_lp 'Short Path km'
              Returns 'Long Path km'.

              Both are floating point values.

EXAMPLES

       Start rotctl for RotorEZ using the first serial port on Linux:

       $ rotctl -m 401 -r /dev/ttyS0

       Start rotctl for RotorEZ using COM2 on Win32:

       C:\> rotctl -m 401 -r COM2

       Start rotctl using rpc.rotd and querying the position:

       $ rotctl -m 101 -r localhost \get_pos

       Connect  to  a running rotctld with rotor model 2 ("NET rotctl") on the local host and specifying the TCP
       port on POSIX:

       $ rotctl -m 2 -r localhost:4533

       and on Win32:

       C:\> rotctl -m 2 -r 127.0.0.1:4533

DIAGNOSTICS

       The -v, --version option allows different levels of diagnostics to be output to stderr and correspond  to
       -v for BUG, -vv for ERR, -vvv for WARN, -vvvv for VERBOSE, or -vvvvv for TRACE.

       A  given  verbose  level is useful for providing needed debugging information to the email address below.
       For example, TRACE output shows all of the values sent to and received  from  the  radio  which  is  very
       useful for radio backend library development and may be requested by the developers.

EXIT STATUS

       rotctl exits with:
       0 if all operations completed normally;
       1 if there was an invalid command line option or argument;
       2 if an error was returned by Hamlib.
