problem in coding for GSM interfacing using serial port
i am having some coding problem in c for interfacing the GSM module through serial port. i want to send/receive sms. i have done all the setting for the port and know the AT command to use in this but i am actually having problem in reading and writing from serial port how to handle the signal when a msg is received and to send the AT command to the GSM kit.
i need coding for reading and writing the the serial port, and how to send the AT command to the kit.

iscc(7) Miscellaneous Information Manual iscc(7) NAME
iscc - serial communications interface SYNOPSIS
controller iscc0 at isa0 DESCRIPTION
An onboard Zilog 8530 DUART provides AXPvme-based Single Board Computers with console (CON) and auxiliary (AUX) serial communications ports. Both serial communications ports can operate at baud rates from B50 to B38400, excluding B134 (see tty(7)). On AXPvme Single Board Computers configured with a graphics head as the system console, the CON serial communications port (/dev/tty01) is available for use by application programs as an additional communications port. In the absence of a graphics head, the CON serial communications port (/dev/console) becomes the system console. When used as the serial system console, the CON serial communications port always operates at 9600 BPS, 8-bits, and no parity. Regardless of system console, the AUX serial communications port (/dev/tty00) is always available for use by application programs. RESTRICTIONS
Data communications equipment attached to the CON serial communications port must be set to 9600 BPS, 8-bits, no parity when configured as the serial system console. The iscc terminal driver enforces this restriction. No modem control is supported for either the CON or AUX serial communications ports. FILES
