Jason;
Ain't got no stinkin modem.
Ain't got no stinkin control lines
Ain't got no stinkin flow control
Just three wires at each end. a. TxD & b. RxD and c. SigGnd
a. & b. swapped in the cable. ie the world's simplest null modem.
wouldn't use the stinkin SigGnd but I hate sparkin and flashin and popin.
<LOL>
