Null modem lead is a serial cable which is most commonly used for connecting two computers (eg in order to transfer files).
They can be purchased in any computer spares shop.
Or you can make them. Schematics abound on the internet. Do a search.
The 9 pin version has female connectors that are wired as follows:
2 - 3
3 - 2
4 - 6&1
5 - 5
6&1 - 4
7 - 8
8 - 7
Incidentally, all such info (wiring for cables, connectors, etc etc) is available in "The Hardware Book".
The page for a 9-pin to 9-pin null modem cable as described above is here:
There are other variants of course, since 25 pin serial cables also exist. All also in that hardware book.
