I'll go along with that. I have one, and I
use it a lot more than my
fancier RS232 test gear (like a Tekky datavoms terst). It's so easy just
to plug in the LED tester and see (as you said) which pin the thing is
transmitting on, which handshake lines is seems to be driving, and so on.
I bought mine over 20 years ago. It failed after about a week due to the
_terrible_ soldering on the PCB. I resoldered everything and it's been
fine ever since.
Add to that the little RS-232 "patch boxes"--one male, one female DB-
25 and a PCB in between with pads for each conductor and a hood that
covers the whole works. I have several pre-wired and labeled with
things like "null modem" "crossover", etc. I even have one labeled
"Laplink parallel". Get enough of these and all you need are
straight-through cables--and maybe a gender changer or two. No
fooling around looking at a cable and saying "I wonder what this is
for..."
Yeah, I have a few double-ended adapters with the connections labeled on
them, but one of these days would like to get my hands on one that you can
patch with jumpers. I've seen those jumpers for 0.025" square posts in
catalogs, but have yet to get my hands on any of them, or a suitable
adapter to use 'em with.
Not that I'm doing all that much with rs232 stuff these days anyway... :-)
