You'll need to develop a hack, which wraps around one or more of the system
calls. The developer guide included with HackMaster (www.daggerware.com)
can provide more details.
>From posts on this forum, the keyboard drivers tend to use the HotSync
interrupt -- a keypress generates one of these, the driver does the first
intercept, sees that its a keypress, and turns it into a character stroke.
If its a real HotSync, they let it go through to the OS for normal
processing.
