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
