[RSM] Serial Port Testing Question

[Jack Parker]

I hope this is not too far off topic but Shelley and I would like to get 
back on for some contests (RTTY/CW focus) so thought we would ask.

Can anyone suggest a means of testing whether a serial comm port on a 
rig is functional? In my case it is a Kenwood TS-570D with a male DB9 
connector on the rear panel. I have a USB/RS232 adapter (no, not an 
FTDI) that is recognized by all our computers but will not talk to the 
rig with either N1MM Logger+ or N3FJP's ACLog. My test bench is 
non-existent, save for a hand held DMM.

Unless a command string can be generate manually, I am pessimistic any 
solution is possible. Any suggestions are appreciated, even if they lead 
to a negative result.
