- Looks like your cable is wrong. The Mac 512 9 pin serial connector differs
- from the PC 9 pin serial connector. Get hold of a special cable for the Mac
- 512 or make one yourself. The shareware communication program Zterm has a
- doc file with a description of the cable for a mac 512 9-pin to modem 25-pin
- connector. (If you can't get a copy of that, mail me)
