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.
