   I've long been of the opinion that getty needs a serious rewrite.  For 
instance, my SCO Unix feed has both 2400 and PEP lines, but my login script 
must send a number of BREAK signals to tell uugetty to toggle baud rates.  
The number of BREAKs needed depends on many things, including line noise at 
connect.

   Only recently have I managed to get a decent uucico working with my 
brain-dead PC software, allowing me to put conditional sends into my login 
scripts(!)

   Even so, the time it takes for getty to react to a break varies, so I must 
put in long login chat timeouts... unfortunately, in many cases, it would be 
to my advantage to reduce those timeouts if at all possible (e.g. no point 
waiting a minute to figure out that CARRIER isn't going to show up if the 
system's busy)... all of this would be solved if getty had the ability to 
recognize connect strings sent by the modem.

   To bring our gripes together, it would be nice if getty could 
re-initialize the modem periodically using a user- (oops, sysadmin-) 
configurable string, much as the Mess-DOS BBS programs currently do.

P.S.: Incidentally, I was surprised and pleased to read a few months back in 
the SCO *ix docs that dialout scripts can now be told to watch for baud rates 
reported in the CONNECT string.  These scripts, though not as efficient as 
dialer binaries, seem a *lot* friendlier and would be by far my choice when 
configuring a new modem.  Heck, *patching* DialTBit.c was hell...
