The entry "D2400" says to output the login banner at 2400. If the user presses the BREAK key, getty switches to the next speed (1200 baud) and types "login:" again. It is expected that the user (or uucp chat script) will send BREAK signals until the "login:" prompt shows up ungarbled. This works, and I have used it this way. I have not tried the "ab" parameter in gettytab. The lines in /etc/gettytab # Auto-baud speed detect entry for Micom 600. A|Auto-baud:ab:sp#2400:f0#040: sort of imply that "ab" works only for Micom modems.

However, I got it to work on a directly-connected terminal at Sun. The comment comes from 4.3BSD, so you'd have to ask the Berkeley folks what it's doing there.
