Todd:

I would suggest that when compiling the module which contains your isr that you
should use the -Gs switch on MSC. This removes the call to __chkstk in the
generated code.

This is also a good idea when doing TSRprograms, too, since they often run
with no stack, or lean on DOS or their "host" program for stack space.
