GSM driver exposes itself as a UART or USB ..

Hi,

A GSM will be connected to UART or USB of a PDA . Now I?m going to write
a GSM driver on PCMCIA and claim the hardware resources etc, but exposes
itself as a UART or USB. Of course PDA will be running WinCE, but
assuming that windows is used, is this possible in windows? Any clue,
hint or any link is available where I can get more information?

Regards
Esha

Wrong approach. GSM will not claim hardware resources. It is the UART or USB
host who will.

So, its like the GSM modem gets connected to a UART or USB port. And a UART/USB based GSM
driver has to be written. When this driver gets loaded, either it can use an unused com port or
can create another com port. Am i correct ?

If your device is installed under the modems class, a com port name will
be generated for you. There is no need to worry about com ports or
their names. Just focus in your driver on support the serial IOCTL
interface and mapping it to your device.
