Ok folks, I have just built this cable:

http://www.netbsd.org/Documentation/Hardware/Misc/serial.html

		Modem MiniDIN8 to DB25 (Macintosh, non-null modem)
		Note that RxD+ is shorted to ground, and that TxD+ and GPi
are floating. You should have the short as close to the DB25 as possible,
instead of near the MiniDIN8. If possible have the RxD+ and RxD- as a
twisted pair. 
		MiniDIN8           DB25
		--------          ----
		1 HSKo ----------- 4 RTS
		2 HSKi ----------- 5 CTS
		3 TxD- ----------- 2 TxD
		5 RxD- ----------- 3 RxD
		4 GND  ---+
		          +------- 7 GND
		8 RxD+ ---+
		6 TxD+ ---x
		7 GPi  ---x

What on earth is going on?

I've tested it on both printer and modem ports on the mac, Ive had the pc
set to 38400 8N1, 9600 8N1 - tried it on two different
Pc's - and nothing!

What am I doing wrong people?

James
