LINUX-RPM: Verifying the ports

To test the installation, you can use the terminal program ‘minicom’. Use the command “minicom -s” to set up the tty port that you will use to communicate.

1.In the Configuration window, select “Serial Port Setup.”

2.Select A to set the Serial Device (for example, /dev/ttyM1a).

3.Select E to set the baud rate.

4.Press Escape (Esc) to exit.

5.Select Exit to communicate with the port.

6.Issue AT commands and make sure it returns “OK”.

LINUX-RPM: 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. Normal ports (ttyM) are configured for dial-in connections.

In these expressions (ttyMxy), 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

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
