Just a side-note - this is often true of parallel ports, too,
particularly add-in's. Logic 1 may be 5 volts, or it may be 3.3. I had
an add-in port that wouldn't work with one of my band decoders, because
of this difference.
Since both hardware serial and parallel ports are on the way out, it
would be interesting to know if USB adapters powered from the motherboard
are standardized on 5 or 3.3 volts, and if they deliver whatever maximum
voltage the motherboard gives them to the serial output.

although
it works fine with everything else, just wasn't shouting loud enough to

any response from the rig. I switched to an old tower computer and the
rig
talks to it fine, never a problem.
Perhaps your home brew serial port is just 'on the edge' of your rig's
signal level requirement. If it is, the only fix is a different (higher
output) serial port.
I remember muttering what about the RS232 standard, and being advised
that
it is often referred to as the RS232 non-standard...
Just a thought
