[comp.sys.mac.wanted] hardware handshaking on mac plus and new macs?

ok, HOW can you do Hardware handshaking on a mac plus?
(or on a Classic, LC, or Si)  None of these has Pin 7
(known as GPi or general Purpose input)  hooked up
(apple got cheap and figured it wasn't neccessary)
thus you can hook up hardware handshaking but you lose carrier detect
(which is not acceptable!!!)
Can you use pin 8 - which is the extra receive pin
for carrier detect if the software is right????
if not, any other way???

thanks in advance,
Seth
