I think there is a small bug in pppd.  When two ppp lines are started like:
  ifconfig ppp0 up
  ifconfig ppp1 up
Then two lock files will be generated in /usr/spool/uucp/LCK... that are
owned by pppd.  This is as it should be.  BUT after:
  ifconfig ppp0 down
Then BOTH LOCK FILES are removed.  This is a problem if getty is sitting
waiting to get into the act.  Now I have getty playing with ppp1's line,
as well as ppp0.  Result, bring one line down and loose both, or don't allow
login on the ppp lines.  Set up the network for connections only in one 
direction.

Next Problem, still pppd.

If carrier is lost on the ppp line, pppd doesn't care!  He just sits there and
sends his packets to the modem blindly.  When the line finally times out
after idle=n then he will drop the dead line and re-start it.  This works but
if idle=60 to keep the line up most of the working day, this is a problem.

Does anyone have a solution to either of these problems PLEASE?
Please email if you can.  Digex (my connection) is having a problem with
the biz.sco groups.  I should be able to see all the ppp group's postings.

John,
Check your configuration of the sco machine and your modem to be it is
set up to recognize Carrier Detect (CD) line on the RS232 interface.  If
your using a Hayes compatible modem, see if &C1 is set.  Might also want
to check to see if &D2 is set to 'reset' the modem when the sco system
drops DTR.  In the pppd config options, check to be sure 'modem' option
is included.
I use these options on a Sun running 4.1.3 and everything works great!
