View, CA (415) 960-7300 Lines: 25 I'm currently having big problemtrying to talk to other computers with my Mac IIcx and Racal Vadic 9632 VP V.32 modem. Someone on the net mentioned that the problem with high speed communications and the Mac is that there just aren't enough control lines... i.e. you cannot use hardware flow control on the Mac serial ports. This seems unlikely since Apple does provide lines "Handshake In and Handshake Out" on the serial port, although the exact meaning of these names is quite vague. Question: Can I use the Mac with my high speed (9600 bps) modem? Can the Mac IIcx support hardware flow control? WHAT ARE THE EXACT PINOUTS OF THE CABLE I NEED and how should I configure the Mac and modem to make them talk with erach other properly? I have no problem swith 2400 bps communications. When I take it up to the high speeds, nothing works.
