    What OS? What do you mean by "module"?
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge

    My OS is WindowsXP.

    This "module" is a receiver. it receives Information from an digital thermometer.
    Now i have to get that information which is sent to that module and is connected to the com port. That information are only bits or bytes which i have to decode with a protocol i got here.

    You should be looking at some of the Serial Programming on Windows Platform.
