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.

sredird
sredird(8) sredird sredird(8) NAME
sredird - RFC 2217 serial port server SYNOPSIS
sredird [-i] log-level serial-device lock-file [poll-interval] DESCRIPTION
This manual page documents briefly the sredird, program. This program when run through inetd will use the RFC 2217 extensions to TELNET to implement serial commands over the TCP connection and interface to a specified serial port. OPTIONS
An optional first parameter is '-i' to enable compatability with Cisco IOS. The first mandatory parameter is the log level for use in syslog. The next mandatory parameter is the device node for the serial device, it must be a fully qualified path. The final mandatory parameter is the file name for the lock file to be used to prevent multiple instances of sredird from talking to the serial port at the same time, or to allow sharing a port between modem and sredird. EXAMPLE
Here is a configuration line for running it from inetd: sredir stream tcp nowait root /usr/sbin/tcpd /usr/sbin/sredird 5 /dev/modem /var/lock/LCK..modem AUTHOR
