From my (now ancient) notes, you should be able to build a servicable cable with hardware handshaking capability from the info below. Apple //c 5 pin DIN DB25 DB9 "AT" style 1 (1) DTR Data Terminal Ready -> 6 DSR 6 DSR 2 (4) TD Transmit Data -> 2 RX 2 RX 3 (2) GND Signal Ground - 7 GND 5 GND 4 (5) RX Recieve Data <- 3 TD 3 TD 5 (3) DSR Data Set Ready |-> 20 DTR 4 DTR |AND 5 CTS Clear To Send 8 CTS My notes remind me that some 5 pin DINs have non-sequential numbering. These numbers are in parentheses. -- Michael Hickey, Canberra, Australia | --x-- sirius@spirit.com.au |
