I am writing an extensive library of tsr applications and a standard tsr management library set of routines. I am attempting to do it 100% in TurboC 1.5. All is going very well, except I can not seem to capture interrupt 21 without the machine crashing. - Capturing all other necessary interrupts works just fine. I need to capture interrupt 21 and preserve all of the registers on call and return (int 21 calls use just about everything including DS). Has anyone succeeded in doing this in TurboC? If so, can you send a code fragment or some hints? Thanks Phil Kaufman Silicon Compiler Systems ...{decwrl} !sci!phil
