Yes, this is possible. After loading EPICS core run "veclist" to find out
the symbol name of the routine that is attached to the interrupt in
question.
Use intConnect() (C source code) or intVecSet() (assembler) to attach
your code (which will call the original ISR attached to the interrupt).
Note that there are only a limited set of vxWorks system calls that can
be safely invoked from within an ISR.
