    Strange - almost exactly the same wording as this older thread.

    I don't know much Linux, but I've done serial port communication in Windows.

    There's a library linked on this thread, though I just found it now and never used it, so I can't tell you if it's any good. The point is, there is a lot of information out there if you just search.

    [edit]

    (full source code)
    It's not very likely you'll get someone to write the entire code for you. Please review the homework policy of these forums.

    You can't magically open “linux c” which will open a program to receive the data, when you receive data through the modem cable. It seems like you need to be running a program that will listen for data on the modem cable. This is usually done with Unix-like systems by calling socket followed by read, so you might want to look at both of those functions.

    Consider getting a text editor. I like Vim, but there are many others as well.
