There is a work round which is fine with Icom radios,
and possibly others that have discrete addresses.

Use a second serial port and a second RS232 - TTL
adaptor (CT17 etc). Then parallel the CI-V lines to
the radio which will now respond to commands from
either port. If both ports try to communicate with the
radio simultaneously garbage will result, but the
radio does not respond unless it gets a full clean
message and collisions will be quite rare if WL is
only set to interrogate every 500ms.

This does of course require (1) Icom radios (2) an
extra serial port and (3) another RS232 adaptor so I
have not really answered the question....
