Introduction
This appendix explains how to verify that the Multitech MT9234ZPX-UPCI modem has been detected in Linux
Operating System running kernel 2.6.xx.
Assuming that the PCI card has been already installed in the system.
Logon to the system as root.
To check which kernel version the system is running, send the following command
You should get a response like this:
[root@armadillo ~]# uname -a
Linux armadillo.net 2.6.18-8.el5 #1 SMP Thu Mar 15 19:57:35 EDT 2007 i686 i686 i386 GNU/Linux
This particular system is running kernel 2.6.18-8.el5. For Multitech MT9234ZPX modems, Linux will use a native
driver for the PCI interface already contained in the kernel. Once the system detects the modem it will assign 2 new
ports to the system. Due to the nature of the interface used, two com ports will be added, but only one com port will
be use to access the modem (first port). If you use the second port, the modem will not respond to any AT
command.
To see how many ports the system has detected on boot. Send the following command:
You should get a response like this:
The new ports detected and assigned to the card will be labeled as follow. The IRQ and the I/O address might be
different in your system.
Remember, accessing the modem, you need to always use the first port.
To verify if the modem is operational, you can use the most common terminal emulation in Linux called minicom.
Enter minicom -s
