How to set up MBSE for ISDN.                      (J. Beekhuizen, 2:280/1018)


Of course, you have to configure and build your kernel for ISDN support
and the correct drivers for your card.  It is beyond the scope of this
document to explain how to do that.

To your /etc/inittab file add the following lines for your ISDN devices
ttyI0 and ttyI1.

     # ISDN lines
     I1:23:respawn:/usr/local/sbin/mgetty -x 4 -i /opt/mbse/etc/issue ttyI0
     I2:23:respawn:/usr/local/sbin/mgetty -x 4 -i /opt/mbse/etc/issue ttyI1


To your mgetty.config file [/usr/local/etc/mgetty_sendfax/mgetty.config
on my system] set up the ttyI0 and ttyI1 ports.  With AT&E you set the
MSN/EAZ the device should listen to.  This should for an MSN be your
telephone number _with_ the area code but _without_ the leading 0.  For
an EAZ the last digit of your EAZ.  

     # The ISDN ports

     port ttyI0
     modem-type data
     init-chat "" ATZ OK AT&E714015437&W0 OK AT&B512 OK

     port ttyI1
     modem-type data
     init-chat "" ATZ OK AT&E714017198&W0 OK AT&B512 OK


From the mbsetup menu #5 "Edit Modem types" configure the ISDN modem
type.
