- The one that comes with the supra works pretty well.

- : Make sure you are using the "at&f1" init string.
- This is correct. Most mac serial cables don't support DTR hangup,
- so the PC defaults wont work as well.

- Close - the problem does sound like DTR was going low and making the modem

- nothing to do with the handshaking. 26.4K/24K is actually a good speed
- if you are using Southern Bell or similar quality phone lines.
