I am trying to implement a write to screen function redirectable with the
printer that is capable of writing only to a certain subsection of the
screen. This is for an assembly-language application. Since it can only
use a part of the screen it seems like we have to use the BIOS int 10h
functions for the actual i/o, but in order for it to be redirectable, it
seems like it would have to take the form of a DOS device driver.
I have 2 questions about this.
Is there a generally available source wherein this has been done before so
that I don't need to reinvent the wheel?
Is there a better (simpler) way than a device driver to implement this?
