I could explain the behaviour if he's using kppp in conjunction with
pppd-2.3.6 or higher. kppp from KDE 1.1 binds stdin/stdout the serial
device _and_ explicitly specifies the /dev/ttySx in the command line.
This leads to some trouble with the recent pppd's since will sent its
debug output to the serial port this way. The solution would be to
disable all debugging (see kppprc), get the most recent version from
ftp.kde.org or wait for KDE 1.1.1.
Harri.
P.S. The current versions don't pass the tty via the command line
anymore. This lead to permission problems with the new pppd anyway (it
drops it's suid status before opening the device).
