That does NOT solve one problem:

o You dial out on the non-modem control port.  The call completes, then
  drops.  How do you detect it?  The answer?  You don't!

The fix?  Below is a shar archive.  Unpack, read the comments, compile and
go.  This will work on ISC 2.2, 2.0.2, and should work on SCO Unix V/386
(but it has NOT been tested there).  There is one hack in the code right now:

	ISC does not correctly support CLOCAL on modem control lines.  If
	you open a port with O_NDELAY, then set CLOCAL and clear O_NDELAY
	with fcntl, you should get BLOCKING reads with the CD signal
	ignored.  Instead you get non-blocking reads if CD is low, and
	blocking reads if CD is high (idiots!).  Thus, there's a timer-read
	routine in here; it'll work if and when ISC fixes their driver, and
	works ok as is now (but does consume a couple seconds of runtime per 
	hour when the port is idle).

	Unfortunately, Equinox and a few other board makers have mimiced the
	broken code instead of fixing it (double idiots!)  Thus this hack.


Note:  This code is NOT PD; it's Copyrighted.  It can be used
  	non-commercially, but if you want to sell it or enhance the value of
	a commercial poduct you have to get a distribution license.  Flame
	if you must, use the code if it helps you.

	This program is still a little messy, but it certainly functions.
	We run all our modems at "ddsw1" with this and have no trouble with
	it at all.

X/*	Autobaud program 
X
X	Run in place of 'getty', this will prompt for a name
X	and call login just like the old one used to do... Only
X	difference is that it is rather interesting in it's interpretation
X	of what a 'gettydefs' file is; that is, there isn't one.
X	
X	We use modem return messages to determine the baud rate.  Locks are
X	respected as well, allowing the uucp system to share the ports.
X
X	The issue file is in /etc/issue.new.  The first line of this file
X	contains the login prompt.  The remainder is the banner message.
X
X	You invoke this with:
X		/etc/autonew ttyA2 [code]
X	
X	from /etc/inittab.  "[code]" is the numeric code for the baud rate
X	to send the initialization string at -- most of the time  you want
X	this to be the highest baud rate your modem will support.
X
X	Notes:
X		1) The device name does not have a prefix.  It is prepended
X		   automatically (/dev/ is added).
X		2) For ISC, use the MODEM CONTROL PORTS.  This program can
X		   interlock with UUCP; see their DEVICES file for the
X		   proper flags to set in the DEVICES and DIALERS files.
X		   Use the "new" definitions which have ",M" added (see your
X		   documentation for details).
X		3) While a port is being used for dialout, it will show
X		   up in a "who" command as "_Dialout".
X		4) Modes will be changed on ports to prevent random users
X		   from using the ports for "cu"s and other communications
X		   uses.  This can be easily changed if desired (look for
X		   the "chmod" call in the source).
X		5) The file /etc/autobaud.parm must be present.  The format
X		   is as follows:
X			First line -- initialization string for ports
X			Second line -- response to initialization string
X			Rest of lines -- baud codes, rates (text), and
X					 response strings expected.
X
X			Baud codes are the speed codes from termio.h; 
X			11, for example, is 2400 baud.
X
X		An example /etc/autobaud.parm file:
X			
X		AAAAATE0Q0V1
X		OK
X		7 300 CONNECT
X		9 1200 CONNECT 1200
X		11 2400 CONNECT 2400
X		14 19200 CONNECT FAST
X	
X		
X		6) Your I/O board and/or drivers MUST correctly support the
X		   notion of O_NDELAY.  In addition, you have to be able to
X		   turn on and off the NDELAY flag with fcntl.  LOTS of
X		   intelligent boards broke this; if it's broken this
X		   program will NOT work.  ONE HACK:  If your NDELAY
X		   interpretation returns non-blocking if CD is down (with
X		   CLOCAL set and NDELAY cleared) this program will function
X		   correctly, although it will eat a small portion of CPU
X		   time to do so.
X		
X		7) Autobaud will wait for a carriage return and use it 
X		   to determine the parity of the caller's terminal (either
X		   8/N/1 or 7/E/1 only).  If the user doesn't press anything
X		   within a reasonable time frame, 8/N/1 is assumed.  The
X		   message "CONNECTED" is output to the user terminal
X		   immediately after autobaud senses the user's baud rate.
X
X		8) All modems served by this have must use the same response
X		   sequences, although subsets are permitted (ie: the
X		   example file above would work for a USR Courier 2400 and
X		   a Telebit Trailblazer Plus equally well).
X
X	CHECK THE FUNCTIONS "checklock()" and "makelock()" -- they may need 
X	to be modified for your system!  In particular, some systems use 
X	binary PIDs and/or store the lock file in a different place.  We 
X	currently are set up for HDB UUCP on ISC 2.0.2/2.2.
X
X	Note that this program can share a port with a modem dialing out on
X	the same line!  It will perform with uucp on the same port without
X	trouble, so long as the locking is done correctly by uucp and other
X	programs which expect lock files.
X
X	Autobaud removes any stale lock files it finds automatically.
