If you disable ttymon with admintool, or pmadm, that should only effect
dial *in* service.  (no getty is running, basically)  While I haven't
used used sun's PPP in a while, I was using the dpPPP package sometime
ago without too much trouble both for dial in and dial out under
Solaris 2.5. (see below)

For dialin, I really recommend using HylaFAX to launch ttymon.  That's
what the dire warning is about.

However, unless this changed in pl2, or perhap Solaris 2.6, there is a
problem with the way HylaFAX does the UUCP locking under Solaris.
Sometimes, HylaFAX while not see the fact that another process has
grabbed the modem for dialout.  You can check this by running faxstat
while doing a dialout PPP or UUCP operation.  If it doesn't report
something like "waiting for modem to become free", you may have a
problem.
