I'll There is a bug in the DJGPP v2 library: it defines `stdprn' as using file handle 3 and `stdaux' as using handle 4, whereas it should be the other way around. So when you fprintf to stdprn, it actually tries to write to the COM1 port, with the obvious results. To correct this, compile the files `stdprn.c' and `stdaux.c' below and put them into your C library, like this: gcc -Wall -O3 -c stdprn.c gcc -Wall -O3 -c stdaux.c ar rvs c:/djgpp/lib/libc.a stdprn.o stdaux.o ranlib c:/djgpp/lib/libc.a and print happily ever after by writing to stdprn. > In my Borland and other 16bit versions I just wrote to stdprn or opened > a file named "PRN" and voila! Neither solution seems to work. Opening "PRN" or "LPT1" works for me. For instance the following program really prints: Thanks Eli. I'll try this soonest and feed back. -- Art S.
