Serial Port

Where can I get a copy of bios.h? It seems there are many header files under that name, so I need the one that allows me to use _bios_serialcom/communicate with a serial port.

Actually, any way of reading/writing a COM port in C/C++ on Win32 would be much appreciated. I've Googled for this, thinking it'd be simple, but all the results involve huge blocks of code. The Microsoft KB solution sure is nice and simple...and it doesn't work, of course.

Don't bother.

Such it is. But that's what you've got.

Maybe you may find something better here:

Why not bother?

And I've seen that page already.

Because programming for DOS on Windows XP is generally stupid unless you're working in a real DOS environment, in which case your target machine won't be running Windows XP.

CreateFile() can be used in Win32 to access a serial port. Pass "COM1" (or whatever port you want) as the filename. From there, use ReadFile and WriteFile to send/recv data. CloseHandle() when you're done.

If you have the Win32 API reference that comes in a .hlp file, the "Communications" page, and those following, have what you want. This seems to be the corresponding MSDN section.
