I've been teaching myself how to write ISRs (interrupt service routines) and TSRs under DOS. I've read through the book MEMORY RESIDENT PROGRAMMING ON THE IBM PC by Thomas Wadlow and tried some of his example programs. All his programs that grab the keyboard service interrupt (16H) lock up my machine when I try to install them. Looking at the source leaves me with the impression that they should work. I'd post the code, but it's copyrighted, so I'll have to ask those who have access to the book to help here. Any ideas what's wrong?
