	One can inform getty (via gettytab) that a line will be able to
	be speed sensed with a CR.  You will have to add an entry to 
	/etc/gettytab and make appropriate changes to /etc/ttys.  Here is 
	our gettytab entry:

	A|Auto-Baud:\
		:ab:sp#2400:f0#040:

 	This works for speeds from 110-9600baud.  We currently use it
	in association with 64 ports (DHU-11) connected to a Gandalf PACX 1000.
	With the Gandalf, if passthrough is defined, the user will simply
	see the login: prompt at any speed in the range indicated above;
	otherwise CR must be pressed at least once.
