I believe the Alt-255 trick is a keyboard BIOS thing. When the original
PC came out, you could press Alt and enter any decimal number on the numeric
keypad and generate the BYTE with that value. If you want a space,
you enter Alt-032; uppse case A is Alt-065. (BTW, the values had 
to be 3 digit, I believe)

Anyway.. Alt-255 is just a special case of using the capability
of the kb BIOS to enter character codes arbitrarily.
