Because I've been having trouble with Xon/Xoff handshake, I thought I'd give hardware handshaking a try. I have been using DIN to DB-25 adapter cables to hook my serial printers to my Macs. I remember that to use hardware handshaking used to require a special nine-pin serial cable on the Mac side. Is this correct or does a "regular" 8-pin DIN type of cable work? Thank you, PB PS: Is there anyone out there who is successfully using Xon/Xoff in FB3? By successfully, I mean is it successfully stopping the output when the serial device fills up? For me, everything is great until label #50 or so, where data loss occurs due to overflow.
