Appendix C – Upgrading Your Modem

Appendix D – Installing under Linux

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

“uname -a”

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:

dmesg |grep -i tty

You should get a response like this:

[root@armadillo ~]# dmesg |grep -i tty

serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

00:0f: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A

0000:03:00.0: ttyS0 at MMIO 0xcdeffc00 (irq = 169) is a 16550A

0000:03:00.0: ttyS2 at MMIO 0xcdeffe00 (irq = 169) is a 16550A

Bluetooth: RFCOMM TTY layer initialized

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.

0000:03:00.0: ttyS0 at MMIO 0xcdeffc00 (irq = 169) is a 16550A

0000:03:00.0: ttyS2 at MMIO 0xcdeffe00 (irq = 169) is a 16550A

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
