Any computer mode has a disadvantage in needing an extra box and power to
run it. While the power isn't a problem if you're running a generator, if
you're running on battery, I think power draw in standby receive is
significant and may well force you into some strategies to minimize the

My guess is that there is some kind of automatic level
control that's turned on. When you transmit, the computer is hearing
silence, so the ALC bumps the slider up. Sorry, I'm not sure were to look
for it other then in the driver and mixer. Be sure to explore all the
options.

If a straight-through cable is what your interface wants, sure. It's worth
a try. It's highly unlikely you'll blow anything by trying. The serial
port is quite sturdy and forgiving.

I'm guessing that it's a "straight through" cable and it may not care if it's
serial or parallel or whatever. Just ohm it out and see if pin 2 on the female
side is connected to pin 2 on the male side, etc. If everything is pin for pin
on at least pins 2,3,4,5,6,7,8,20 then you're good to go.
I take it you made a change today. Whatever it was fixed it.
