rotd - Hamlib rotator service daemon
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
This program follows the usual GNU command line syntax, with long
options starting with two dashes (`-').
Here is a summary of the supported options:
Select rotator model number. See model list (use 'rotctl -l').
NB: rotctl (or third party software) will use rotor model 101
when using rotd.
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.
Set serial speed to baud rate. Uses maximum serial speed from
rotor backend as the default.
Set config parameter. e.g. stop_bits=2
Use -L option of rotctl for a list.
Use number as the RPC program number. The default is 536873369.
Set verbose mode, cumulative (see DIAGNOSTICS below).
Show summary of these options and exit.
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
# rpc.rotd -m 401 -r /dev/ttyUSB1 &
Start rotd as root for a RotorEZ using COM1 while generating TRACE
# 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 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 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!

We are already aware of the bug in the previous section :-)
