My modem is on ttyS3 and something in the Debian 2.2, appears to be setting the permissions to 0640. I have grepped through the startup scripts in /etc/rc2.d and the scripts in /etc/cron.* for the strings tty and chmod, but not found what's doing this.
I have also been unable to find any clues with Google. Any pointers to teh cause of this problem will be gratefully received. Neil Youngman
