Unknown remote command: ("\\get_powerstat") , when connecting from hamlib (rigctl) or wsjtx

[baryluk]

I am trying to setup gqrx with wsjtx, on Debian linux, both latest stable versions, and I am getting errors on connection, because it looks like hamlib (which wsjtx uses too) by default sends some commands on connection startup. This is \get_powerstat, but gqrx does not understand it.

user@debian:~$ rigctl --version
rigctl Hamlib 4.5.5 Apr 05 11:43:08Z 2023 SHA=6eecd3

user@debian:~$ dpkg -l gqrx-sdr | grep amd64

RPRT 1, which indicates a failure.

This is somehow related, and worth reading on hamlib side: https://github.com/Hamlib/Hamlib/issues/1266

Gqrx already has already implemented a number of commands that are only needed for hamlib compatibility, so I suppose it wouldn't hurt to add more.

On my system, I also see that \chk_vfo is sent and responded to with RPRT 1, but WSJT-X seems happy to carry on after that.

Gqrx has 'u/U DSP' commands and I think it's possible to add get_powerstat/set_powerstat as aliases.

[argilo]

The long command names for u and U are get_func and set_func respectively:

https://hamlib.sourceforge.net/html/rigctl.1.html

get_powerstat and set_powerstat have 0x88 and 0x87 as single-character forms.
