Int 21/AH=06h

AH = 06h
DL = character (except FFh)

Return:
AL = character output (despite official docs which state nothing is
returned) (at least DOS 2.1-7.0)

Notes: Does not check ^C/^Break. Writes to standard output, which is always the screen under DOS 1.x, but may be redirected under DOS 2+
