StdAux and StdPrn standard handles (was: The importance of error code backwards compatibility – The Old New Thing – Site Home – MSDN Blogs)

Posted by jpluimers on 2012/04/12

Coo, I never knew that MS-DOS had STDAUX and STDPRN, I only knew about PRN (I think it mapped to LPT1).

Don’t you love the old new thing :)

The standard MS-DOS file handles are as follows:

handle name meaning
0 stdin standard input
1 stdout standard output
2 stderr standard error
3 stdaux standard auxiliary (serial port)
4 stdprn standard printer
