flexfax: Experience: Adaptive answer PAP PPP, PROLiNK 1428LE

[Leon Kos <leon@lecad.uni-lj.si>]

This may be useful for owners of subject modem and PAP PPP interested
people:

We are uning FreeBSD for HylaFAX with adaptrive answer for FAX and 
DATA. Instead of getty we are using /usr/sbin/ppp program for DATA calls.

Modem used is  PROLiNK 1428L which is somehow broken when using adaprive
answer in class2. The work around is to force class0 when ring is detected
and to wait tor connect string. Configuration is the same as with rc288dpi
with the following differences:
AdaptiveAnswer:         yes             # enable adaptive answer
ModemAnswerCmd:         AT+FCLASS=0;A   # tricky for class2
ModemWaitForConnect:    yes             # needed because DATA is first response

PPP with PAP:
I have done normal instalation an then binary patched faxgetty with emacs 
hexl-find-file and replaced string /usr/libexec/getty with /usr/sbin/ppp.
This can also be done with editing configure script but why bother.

config.cuaa0 file is changed for arguments:
GettyArgs:              "-direct PAPServerwithPASSWD" # PPP arguments

Aditional the  /etc/ppp/ppp.linkdown file must contain:
PAPServerwithPASSWD:
 quit all
