I recently got a source code of a program for serial communication (via COM ports) and as I tried to compile it in MS Visual C++ 6.0 it says "Cannot open include file: 'bios.h': No such file or directory"
Sure enough, I couldn't find it in include directories. Then I downloaded Dev-C++, DJGPP and Borland 5.5 compiler but none of these seem to have the bios.h and it's library.
What am I to do? Is there a free compiler that has this library and header? Or is there a better way to fix this problem? I'm a C beginner, so wouldn't know which other libraries include functions that do the same as those in bios.h...
