/etc/gettytab entry:

dial.115200:\
        :np:to#30:sp#115200:pp=/usr/sbin/pppd

>Description:

	
With the timeout option enabled in a gettytab entry (:to#30:) and pppd 
invoked when getty automatically detects a ppp header, pppd dies with
SIGALRM when the timeout occurrs.

>How-To-Repeat:

	
Add the ':to#30:' option to a getty dialup config.  Set the 'pp' option to 
automatically start pppd when getty detects a ppp frame.  Pppd will then
die when getty should have died due to a timeout.

>Fix:
	
	
Apply the following patch to main.c of the getty source.  This patch is 
relative to -current as of May 31, 1997.
