I am writing a TSR program in assembly language for MS-DOS 3.xx that requires knowing the video mode from time to time. Polling the video mode via int 10h is unacceptable, however, I can poll a variable. My understanding is that I can rewrite the vectored interrupt for int 10h to jump to a location, update a variable and jump to the normal int 10h location. Since I am not familiar with writing code to do this, would someone please indicate how to do this or preferably write a procedure/subroutine to do it. Please forward any responses to jelynch@hubcap.clemson.edu since I do not use vnews on a regular basis. Thank you, J Lynch:
