Having recomended a complex piece of test gear in

I'll recomend something simple that I wouldn't like to be without - a
'Christmas tree' type RS232 tester. One of those little in-line adapters
with red/green LEDs on the major lines (TxD, RxD, RTS, CTS, DSR, DTR,
CD).
An absolute must for anyone working with RS232 serial signals!
It also makes sense to get one that also has jumpers.
IMHO
