freebsd/usr.sbin/pppd/pppd.h
Paul Traina 7e31b4b1be Previously, if the dial script had any problems, pppd would simply 
bomb out.  Unfortunately, FreeBSD's sio driver and certain internal
modems don't get along very well, which can cause the serial port to
wedge until it is closed and reopened.

Add new variable, connect-max-attempts, default = 1 (to mimic previous
behavior).  If > 1, will try up to "n" times to dial remote site before
aborting.
