Hello,
I want my program should trigger an interrupt when the data is received on the serial port.
Please tell me how to handle this in C or C++.

thanx

register a signal handler for the signal that is generated when there are some operations or data flow in the desired serial port.

Hope this helps.

Use sigaction() to catch a SIGIO signal on the filedescriptor that has the serial port open (e.g. /dev/ttyS0), or see this thread for this thread for an example how to have your program sleep until the serial port needs attention.
