Linux MT5634ZPX-PCI Installation.

Linux generally uses a port format of "ttySx" using 0-3 in place of the "x". The port ttyS0 is equal to Com Port 1. Port ttyS1 is equal to Com Port 2, and so on.

Other than the steps in parts III and IV, the installation is generally the same as for other modems.


Here is how you get a MT5634ZPX-PCI PCI modem to work under Linux:

I) Physically install the modem.

II) Login to your system as "root".

III) Determine the resources used by the modem. To do this, look at your /proc pci file with a command something like this:

"less /proc/pci".

IV) Look for an entry that has vendor id=11c1 and a device id=480. Note the IRQ that this device uses as well as the first I/O address that is listed. The address will be similar to "0x7c00".

V) Use the IRQ and I/O address obtained in step IV to set up the serial port that the modem uses with a command like this:

"setserial /dev/ttySx uart 16550A port y irq z autoconfigure"

where x is the serial device you want to use, y is the I/O address and z is the IRQ.

VI) You will want this command to execute each time that your machine boots, so you will want to put the command that you typed in /etc/rc.d/rc.local or in /etc/rc.d/rc.serial

If you can't see the new port in an application, you may need to make a symbolic link from your serial device to /dev/modem with a command like this:

"ln -s /dev/ttySx /dev/modem"

where x is the serial device that you choose (like in step V) for your modem.

That should do it.
