[Elecraft] KIO2, KPA100 - is SWR value available via RS232?

[ub5_073_oleg]

David, thanks for your reply!

I gave it a try in a terminal program.

After connection at 4800 baud,
DS;  returns the frequency
SW20;  enters tune mode (I changed the tune mode to CALS to
have enoogh time for the following command)
DS;  returns a "?", although I see the SWR on K2's LCD

Am I doing something wrong? My firmware is 2.04P  1.09
