The "down arrow" key doesn't generate a character.
It generates an ASCII code of 00h, and a keyboard
scan code of 50h.
The only way to simulate a "down arrow" keypress is
to stuff the appropriate codes into the keyboard
buffer, followed by a carriage return.
If your staff programmers don't know how to do this,
they should probably be fired for incompetence.
Since yours is essentially a low-level programming
question, try a programming newsgroup. alt.lang.asm
would be a good choice. And be sure to specify what
programming language you're using.
