Hi Jim,
We used the Courier I-modem for over a year using this option file. I
never had time to play with it much, but we were dedicated on both B
channels, which, of course we were limited to 115200 BPS because of the
serial port settings.
I also never played with the MTU settings, however, I'm about to come up on
ISDN again. Ameritech offers 1 B channel at the same cost of standard
dialup, so thought I'd give it a try.
Attached is the options file, and I included a script I wrote to redial if
it
detects that the link has gone down using ping to check that the other end
of the isdn link was still there. If it couldn't get a response it
shutdown and restarted.
Good Luck...
