The correct command sequences
for selecting antennas are
AN01;? ==> antenna 1
AN02;? ==> antenna 2
AN03;? ==> antenna 3

to read the current antenna selection
AN0;
The response will be
AN010;
AN020;
AN030;
Note that the third and fifth characters are always a zero, not
an upper case P or O.

Hi Robin, Thanks for the answer, not sure what happens when
it switches between vfo's on startup and shutdown, but trying to
see what if anything changes and from where the change comes.
Not sure if there is a bug in flrig but the commands to switch
antenna port do not work,? well not here any way using bookworm
on a pi 4. Though going to try ubuntu 24 later on the pi. The
command for switching ant is ANP21; for ant 1 ANP22; for ant 2
and ANP23; for ant 3. I just? get a response of ?;
