Nah, .. forget the documentation! Save the gray cells and get yourself an
'RS232 breakout box'. Most electronic stores have them, as do most network
vendors. Most PCs use DB9s, but if you can't find a breakout box with DB9s
you can also get 25->9 adapters (just be sure to get the right 'sex').
A breakout box will show if the data leads are crossed - you need to see
'lights' on 2 AND 3 (TX & RX) to know your connection is correct. If
not, just swap 2 and 3. MOST terminals will run quite happily with 2, 3,
and gnd (5 or 7).
Knowing what is actually happening is a lot nicer than just trying one
cable after another.
