       rotd - Hamlib rotator service daemon


       rpc.rotd [OPTION]...


       The  rotd program is a Hamlib rotator daemon that handles RPC client requests. This allows
       multiple user programs to share one rotator.  At this time multiple rotator support is not
       available (help needed!).

       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.


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

       Here is a 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 rotor model 101 when using rotd.

       -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.  Typically /dev/ttyS0, /dev/ttyS1,
              /dev/ttyUSB0, etc.

       -s, --serial-speed=baud
              Set serial speed to baud rate. Uses maximum serial speed from rotor backend as  the

       -C, --set-conf=parm=val[,parm=val]*
              Set config parameter.  e.g. stop_bits=2
              Use -L option of rotctl for a list.

       -t, --prog=number
              Use number as the RPC program number. The default is 536873369.

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

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

       -V, --version
              Show version of rpc.rotd and exit.

       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.


       Start rotd as root for a RotorEZ using a USB to serial adapter and backgrounding:

       # rpc.rotd -m 401 -r /dev/ttyUSB1 &

       Start rotd as root for a RotorEZ using COM1 while generating TRACE output:

       # rpc.rotd -m 401 -r /dev/ttyS0 -vvvvv

       Start rotd as root for a RotorEZ using a USB to serial adapter while setting baud rate and
       stop bits and backgrounding:

       # rpc.rotd -m 401 -r /dev/ttyUSB1 -s 4800 -C stop_bits=2 &


       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

       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  rotator which is very useful for rotator backend library development and may be
       requested by the developers.


       No authentication whatsoever; could be done through domain  restriction,  though.   Please
       ask if stronger security is needed.


       Does not support more than one communication device for multiple rotor control.  (e.g. for
       Single Operator 2 Radio)  Help needed!
