Chapter 3—Driver Installation

The ISI Linux driver creates the following TTY devices in /dev directory:

- /dev/ttyM1a TO /dev/ttyM1p for the first ISI card

- /dev/ttyM2a TO /dev/ttyM2p for the second ISI card

- /dev/ttyM3a TO /dev/ttyM3p for the third ISI card

- /dev/ttyM4a TO /dev/ttyM4p for the fourth ISI card

For the ISI5634PCI-4, it uses the following:

- /dev/ttyM1a TO /dev/ttyM1d for the first card

- /dev/ttyM2a TO /dev/ttyM2d for the second card

- /dev/ttyM3a TO /dev/ttyM3d for the third card

- /dev/ttyM4a TO /dev/ttyM4d for the fourth card

For the ISI5634PCI-8, it uses the following:

- /dev/ttyM1a TO /dev/ttyM1h for the first card

- /dev/ttyM2a TO /dev/ttyM2h for the second card

- /dev/ttyM3a TO /dev/ttyM3h for the third card

- /dev/ttyM4a TO /dev/ttyM4h for the fourth card

Devices mapped for modem cards (ISI5634PCI-4 andISI5634PCI-8 cards):

For ISI5634PCI-4 cards (4 ports):

- /dev/ttyM1a to /dev/ttyM1d for modem ports.

For ISI5634PCI-8 cards (8 ports):

- /dev/ttyM1a to /dev/ttyM1h for modem ports.

LINUX -- 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' 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.

LINUX -- 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.

Note: A base I/O address of 0, e.g., ISIBaseX=oxo, or omission of these parameters for any card X,

disables that particular card.
