Thanks Paul. Earlier today I found an external DB9 port
and cable from an old system and tried it, and as it turns
out the COM2 IDC10 header on the TUSL2 is linear
(AT/Everex type).
Only problem now is, I have a full tower case and need
about 24" from the motherboard header to the DB9
breakout in my case (all PCI slots are occupied so I can't
use a regular bracket). I've spent a few hours trying to
find someone who makes what I need and have had no
luck so far -- all of the IDC10<>DB9 cables currently
for sale are too short. So I might wind up just building
one myself.
Anyway, thanks again for your info!
