Chapter 3—Driver Installation - Linux

LINUX: Setting the baud rate

The 'stty' utility can be used to set the baud rate of a particular port. For example, to set the baud rate of the first port on the first card (ttyM1a) to 38400 bps, execute 'stty 38400 < /dev/ttyM1a'.

The current baud rate can be viewed by executing 'stty < /dev/ ttyM1a'.

LINUX: Verifying the ports

Terminal utilities like 'minicom' can be used to verify the ports, 'talk' to the modem, and dial out.

To configure 'minicom' for a particular port, run it with the '-s' option. In the 'serial port setup' menu option, set the serial device to the required ISI port device (for example, '/dev/ttyM1a' for the first port on the first card). Save the configuration for a particular port using the 'save setup as' menu option as, for example, '1a' for the port / dev/ttyM1a. To connect to the port /dev/ttyM1a using minicom the next time, 'minicom 1a' needs to be executed.

LINUX: TTY Devices Created by the Drivers:

Device files corresponding to ports on the ISI card are created in the /dev folder. Use ttyMxy for normal ports and cumxy for corresponding callout ports. Normal ports (ttyM) are configured for dial-in connections. Callout ports (cum) are used for dial-out connections.

In these expressions (ttyMxy and cumxy), the letter x is the card number (1-4), and y is the port designator (a, b, c, ...).

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
