No!  That is an exact copy of the log file (except for the password of
course).

No.  There is only one line in the pap-secrets file:
# client	server	secret	ip
*		serv1	""	*

Right... everything is setup correctly.  Here is a clip of syslog:

Jun  5 13:41:39 serv1 mgetty[320]: data dev=ttyS1, pid=320, caller='none', conn='115200', name='', cmd='/usr/sbin/pppd', user='/AutoPPP/'

Jun  5 13:52:18 serv1 mgetty[2076]: cannot get TIO: Input/output error

It appears that mgetty is having trouble with my modem--but the modem
isn't the problem.  Any ideas?  It doesn't look like PAM_pwdb failed...???
