I bought a 2400 MNP5/v42.bis modem for my IIsi and couldn't get the hardware handshaking to work, meaning of course that any data compression abilities are meaningless. I read in MacUser that the problem is that the cables are not properly wired, they are impossible to get. Similar 9600 modems come with the proper cables. Anyway there are two options. I bought a new 25 pin rs232 connector and rewired it correctly. I found the proper wiring in my Microphone II manual I think. It was a hassle but it works fine. The other option is to buy a handshaking adapter which goes between the modem and the cable (25 pin). All it really does is jumper a few pins. I couldn't find one anywhere but recently saw it in an Inmac catalog. Hope this helps. Alan Ciemian (aciemian@ics.uci.edu)
