I've encountered similar problems.  Many of the MSC routines will not work
when used in a ISR or TSR.  A good addition to your MSC manuals is an
article on writing TSRs in MSC:

	Christian, Kaare, "Using MicroSoft C Version 5.1 to Write
	Terminate-and-Stay-Resident Programs", MicroSoft Systems
	Journal, September 1988, Volume 3, Number 5, pages 47 - 57.

The software examples in this article are available from SIMTEL in the
