I'm just passing on the not to press a point BUT that cable will not do carrier detect at all since no pin is left to use with DCD (carrier detect - pin 8 of db25) I think it's ridiculous that the mac won't do Handshaking AND carrier detect at the same time. Gimme a good db25 for the mac. Seth Seth Cohn, Service Tech. 607-273-2815 voice 607-272-7002 BBS All things posted are opinions by me, of me, for me, or to me.
