These are SupraFax 288 settings for a Linux Pentium machine. They seem to work quite well for dialup, callbacks and fax. The most important setting for us is S10=254, to avoid accidental disconnections with noisy lines. We use these with mgetty+sendfax.

This list was prepared using at&v

The following are the settings for a Sparcstation 1, with SunOS 4.1.3 (also with a SupraFAX 288 modem). As you can see, the &R and &S are reversed from the previous settings. For some reason, this works better with the getty included with SunOS. We also had to turn off the echo of commands from the modem (E0).
