Hi,

CC: to the mgetty mailing list, as I am no Linux or ppp expert...

I assume you mean /var/lock/LCK..ttyS3, but this is more or less cosmetical.

It will only do this if it doesn't find a valid lock file. For example,
if you create a lock file with "chat"'s process id in it, and this PID
is no longer valid after chat terminates. So, mgetty will try to reclaim
the line, which it can't because PPPd has switched its line discipline
to "PPP".
