You can start with the sample code in v2tk/djgpptsr.zip, available
from the usual DJGPP sites, it shows how to do that.

Note that protected-mode TSRs need functions that are only available
with DPMI 1.0 servers.  CWSDPMI does support those functions, but the
DPMI server built into Windows does not.  So if you want your TSRs to
work on anything but plain DOS, you are probably out of luck.

As for interrupt handling, I think section 18.9 of the DJGPP FAQ list
should give you enough info and pointers to begin coding.
