Adding to that...there are four different versions, depending on the application, as to what null modem cable is needed. Null modem without handshaking Null Modem with loop back handshaking Null Modem with partial handshaking Null Modem with full handshaking. You can find full pinouts here. I have an email into Byon about the cable for use, to see if there is a difference in the configuration null modem and cable for use with a computer and APRS program...see if we can narrow this down without bouncing around like a bead of water in a frying pan. 73 John _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
