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
