On my USR 56k Sportster, the dipswitches 1,3,5,8 are down for the Mac. When I use it on my PC, dipswitches 3,5,8 are down. There is also special wiring in the cable I made for the Mac to ensure hardware handshaking. You can use a standard Mac serial cable, but then you have to specify software handshaking in the PPP setup. The initialization string was specified by USR for the modem also. So I guess I was lucky to have purchased a USR modem for my PC that happens to also work with my Mac.
