Err well,
that's a bit involved. First the Keyboard puts out scan codes to the
PC. The scan codes, well there is one for a key make and one for a key
release. There is/was a micro (8035 one chipper) on the mother board
that translated scan codes ... I think into what you get using get()
scanf, cin and all that c stuff. ASCI II is very limited to err well
a-zA-Z0-9 and a few others. Esentially English alphabet only. Straight
text communications for an ASR33 shaker teletyype 1950 vintage. It
replaced morse code. In a PC there must be lots and lots of character
codes used world wide. All the non English languages plus special
symbols Math, Chemical, Legal, etc. Throw out your ASCI code and figure
out scan codes. If you look up some of the bios calls you should find
them. Better still find an old DOD 1.0 manual from IBM it may list them
for a PC and PCAT which are different.
Hope I've confused the hell out of you.
Regards Ian.
