The problem lies with TC++ (and TC and Turbo-Pascal going back at least 5 years). The stdprn stream is opened as text mode, not binary, so a \x1A acts as an EOF character (just like a disk text file). You need to re-open stdprn in binary mode. I have code (elsewhere) which does this by doing a DOS call via int 21h (from vague memory) because TC won't allow you to change the device's mode. I can post the code (its only about 10 lines) if you need it. Frank. -- Take a walk on the wild side, and I don't mean the Milford Track.
