Chapter 3 - Software Installation
3.16.5 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”.
3.16.6 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. The ISIHP-1S is a special case. It is treated as an
8-port card with only four ports in use. As an example, consider an ISIHP-1S that is the first expansion serial
card in the computer. Ports ttyM1a and ttyM1b are terminal adapter ports; ports ttyM1e and ttyM1f are modem
ports. Ports ttyM1c, ttyM1d, ttyM1g, and ttyM1h are unused and can be allocated to a different purpose after
the ISIHP-1S installation is complete.
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 4-port cards, it uses the following:
- /dev/ttyM1a TO /dev/ttyM1d for the first ISI card
- /dev/ttyM2a TO /dev/ttyM2d for the second ISI card
- /dev/ttyM3a TO /dev/ttyM3d for the third ISI card
- /dev/ttyM4a TO /dev/ttyM4d for the fourth ISI card
• For 8-port cards, it uses the following:
- /dev/ttyM1a TO /dev/ttyM1h for the first ISI card
- /dev/ttyM2a TO /dev/ttyM2h for the second ISI card
- /dev/ttyM3a TO /dev/ttyM3h for the third ISI card
- /dev/ttyM4a TO /dev/ttyM4h for the fourth ISI card
• For 16-port cards, it uses the following:
- /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
