I've been trying to create a TSR that uses both the consol I/O (16h) and the timer (1ch) interupts. When I intercept both, the damn thing hangs. Even if all I do in the 1ch is jmp to the old ISR. Any ideas?

All I can say is that I have plenty of programs that catch these two interupts *plus* int 10h without problem. Can you get your code down to the smallest size which exhibits this behaviour and post it. It's impossible to suggest anything without seeing something. -- D'Arcy J.M.
