3.16.7 Devices Mapped for Hybrid Cards (ISIHP-xx cards):

For the 2-BRI hybrid cards with PCI bus (8 ports; ISIHP-2S/2U)
•
- /dev/ttyM1a to /dev/ttyM1d for ISDN ports. (These four ports correspond to the total of four B-
channels available on the two BRI lines that can be connected to these cards.)
•
- /dev/ttyM1e to /dev/ttyM1h for modem ports. (These four ports accommodate the total of four 56K
modems that can operate on the four B-channels available on the two BRI lines that can be connected
to these cards.)
For the 4-BRI hybrid cards (16 ports; ISIHP-4S/4U/4SD):
•
- /dev/ttyM1a to /dev/ttyM1h for ISDN ports. (These eight ports correspond to the total of eight B-
channels available on the four BRI lines that can be connected to these cards.)
•
- /dev/ttyM1i to /dev/ttyM1p for modem ports. (For the ISIHP-4S/4U, these eight ports accommodate
the total of eight56K modems that can operate on the eight B-channels available on the four BRI lines
that can be connected to these cards. Note, however, that this device mapping for ttyM1i through
ttyM1p does not apply to the ISIHP-4SD. This is because the ISIHP-4SD works with ISDN ports, or
terminal adapter ports, only. The ISIHP-4SD contains no modems in its circuitry).

3.16.8 LINUX-RPM -- Dial-in configuration:

To configure a particular port for dial-in, utilities like 'mgetty' need to be installed on the system. If, for
example, the port /dev/ttyM2c needs to be configured for a remote-access dial-in connection, an entry of the
form 'M2c:12345:respawn:/sbin/mgetty ttyM2c /dev/ttyM2c' needs to be added in the /etc/inittab file. After you
have made the change, execute 'init q' so that the 'init' process re-reads the inittab file and spawns the mgetty
process to wait for an incoming connection. Users can then dial in, use their user names and passwords to log
in, and access their accounts on the machine.
To disable dial-in access on a particular port, change the entry in the /etc/inittab file to 'M2c:12345:off:/sbin/
mgetty ttyM2c'or just comment-out that entry by prefixing a '#' to the entry on the line.

3.16.9 LINUX-RPM -- PPP setup:

The 'PPP-HOWTO' (a document that is available as a part of the 'HOWTO' documentation on most of the
distributions under /usr/doc/HOWTO) explains in detail the procedure for configuring a Linux machine as a
PPP server. This information is also available at
http://www.interweft.com.au/other/ppp-howto/ppp-howto.html.
The documentation in the PPP-HOWTO is directly applicable to ISI ports.

3.16.9 Removing the ISI Driver (Linux-RPM)

1. To remove the ISI driver, type rpm -e isicom
If more than one instance of the isicom file exists in the system, an error message will be returned. To
resolve this, type rpm -q isicom. Press ENTER. All isicom RPM modules will be listed. Decide which of
these files you want to delete. Then type rpm -e filename to delete those files.
