HELP! I need to emulate the keyboard programmatically, that is, generate keycodes (by writing by some i/o port??) that can be read via an IN instruction from the keyboard data port, 60H. The scenario: +-----------------------+ | PROGRAM X | +-----------------------+ +-----------------------+ | RESIDENT PROGRAM Y | +-----------------------+ Program X is running in the foreground and takes over the keyboard interrupt (INT 9). Each time it wakes up via the INT 9 it does an IN instruction from the keyboard data port 60H. When the user types ALT Z, Program X terminates. If Resident Program Y must exit while Program X is running, I would like the resident program to generate the key sequence ALT Z so that Program X exits cleanly, prior to Resident Program Y exiting.
