INT 2F - PTS-DOS 6.51, S/DOS 1.0+ - "EMPTY" (RESERVED FOR INPUT STRING)
AX = 1260h
ES:DI -> string buffer (see getstr)
DL = extended keystroke code or FFh if ENTER
Return: AX = 0000h (default handler in the kernel)
CF set if action done, all registers preserved
Notes: This function is known to be handled by Paragon Technology Systems
PTS-DOS 6.51 and S/DOS 1.0, and probably was also handled
in earlier releases.
The default handler in the kernel justs XORs AX,AX and returns.
This is reserved to be invoked in input string
