this is a code which i have picked up from the internet....
now after i run this code ,i dont any kind of output.as in the code is not able to sense the interupt .that is the reason when it does not read anything coming in from the port.i want to capture the stream of data coming in via the modem through COM3.but the problem here is i m not able get any output for this prog.
Lemme guess, you tried to compile this using some new compiler on some new OS?
Look at the dates - 1990 - that's old!!!!
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
no!!! i have compiled it using Turbo C compiler...
the problem for me is ,i m not understanding wht shuld be the output ideally??
thank u.
you will not see anything on your computer's screen unless you attach something to the serial port that will echo (send) something to the serial port so that the program can capture and display it.
It may only work with MS-DOS 6.X and earlier, or Win95/98. I double it will work at all on Windows 200 or XP.
You may want to capture from the protocol stack instead of directly from the port. You'll need a newer compiler though.
