Hi all,
I am writing a software in C under DOS that handles several hardware
interrupts. Since functions that make DOS calls like "printf" cannot
be used inside the interrupt handler, this is very difficult to debug.
I have found out on the internet that some people use the command
pokeb to display a number or a letter on the screen to make easier to
understand what's going on with the code.
Unfortunately I haven't found the right parameters to use with pokeb.
I don't want to go through detailed VGA programming, I just want an
easy solution to display a character in different positions in the
screen.
Thanks a lot for your help,
Moon
