without installing
 

Hi all
i had connected external gsm modem to cpu.
and also am using iternet connection using GPRS..
its working fine..

but i had not installed any drivers to work that modem..
am using fedora 9.
how it is working with out installing device drivers..

any help it should appreciated

If it is a USB modem then the kernel probably had a driver for the USB interface (which pretends to be a serial RS232-compatible interface). All your dialling program has to do is send the correct dial code to the device (probably /dev/ttyUSB0) and you will be connected. All other important information has already been placed by the ISP on the SIM card.
