In pure linux, you should look for the correct USB driver for your USB modem.

A fast way to test is to do:

-disconect the device
- do a dmsg | grep tty
- note what you get
- insert the device
- redo the dmesg |grep tty
- check the differences.

In some cases USB ports are shown as dev/ttyACMxxx.
Also keep in mind that some USB devices create several tty and in some
cases you can use only one of them to access AT commands and even
another to send/receive messages.

In your windows environment, well, not sure about.

Hope helps

Alvaro
