Hi, in the FAQ, somebody claims that file handle 4 should default to PRN:
http://fd-doc.sourceforge.net/faq/cgi-bin/viewfaq.cgi?faq=incoming/224
Any idea why this would work at all? And why it works in MS but not in FreeDOS? Used language is C.
Look at the definitions in <stdio.h> - stdaux is _iob[3], and stdprn is _iob[4] (Borland uses "_streams" instead of "__iob"). The order of these devices in different in MS-DOS and FreeDOS:
MS-DOS: CON, AUX, PRN, CLOCK$, A:-D:, COM1, LPT1, LPT2, LPT3, CONFIG$, COM2, COM3, COM4
FreeDOS: CON, PRN, AUX, LPT1, LPT2, COM1, COM2, COM3, COM4, CLOCK$, A:-D:
Fortunately, fixing this is very easy. It's enough to swap the corresponding entries in io.asm. Do I need to provide a patch for this?
