I have implemented the following in /usr/libexec/getty: 1) Ability to define a modem initialisation script. The port is opened in non-blocking mode, and a send/expect chat script is executed. If modem initialisation fails, getty recycles. gettytab capabilities: ic=expect send [expect send ...] init chat script ct#val chat timeout in seconds 2) Ability to answer incoming phone calls "manually" which allows disabling auto-answer mode (so the phone is not answered regardless of DTR state). gettytab capabilities: ac=expect send [expect send ...] answer chat script ct#val chat timeout in seconds 3) A recycle time value, to getty to be periodically recycled and initialised after a given number of seconds if there is no activity detected. gettytab capabilities: rt#val recycle time in seconds 4) A "debug chat" script value, which is a bitmask: gettytab capabilities: dc#val debug chat value: bit 0:received data (during chat) bit 1:send data bit 2:expect data bit 3:misc (mainly status) 5) The 'de' capability now removes extraneous input after it pauses, essentially to throw away remaining garbage aftera connection via an answer script. 6) Fixed bugs in the %s, %m, %r and %v macros which don't currently work [uname() was never being called, thus the values for these were always blank. rlogin seems to suffer the same bug]. 7) Sending a sysv-like "issue" file prior the login prompt. This is much more useful than the 'im=' capability since it can be more easily modified by scripts etc. gettytab capabilities: if=<filename> (I saw some chat about this a while back on the mailing list, but alas, no commit resulted). Does anyone have any objecting to me committing these changes? I believe they bring our getty more in line with modem technology that has been available for over a decade now. :-) The changes are fully backwards compatible. A non-modified /etc/gettytab should result in precisely the same behaviour as was present previously apart from items 5 (which should be benign) and 6 (which fixes an existing bug).
