First off, let me say that tonight I cannot reproduce the problem.
What a shock :-)
Why did I do a "Y" adapter. Because I already had a DB9-to-phono
cable that worked. Rather than split off the DTR and GND and run them
to an audio cable I decided to split them off to a DB9 jack and use my
existing DB9-to-phone cable. Six of one and half a dozen of the other.
I could have gone either way.
I already checked for shorts. There are none.
I brought a breakout box home from work today, but now I can't reproduce
the problem. I tried it tonight on 2 machines: a desktop and a laptop and
now I can't reproduce it.
Everything is working fine now. I know I saw that behavior (and no, I
wasn't drinking last night), but it's working now.
