Called as a driver, this program always fails to install, i e it consumes no
memory. Alternatively, it may be called upon as a normal program.

Usage: A>POKE outaddr val [val ...] [outaddr val ...] [; comment]
or:    DEVICE=POKE.COM outaddr ...
outaddr may be either seg:addr (memory address) or Oaddr (I/O address).
All values are in hex, and val is considered a byte if its written as
2 or less digits, or word if its written as 3 or more digits.
val may also be seg@ofs [Ln] to copy data

Example use:

        DEVICE=POKE.COM 40:17 0 ; Switch off Num Lock bit (among others)
        C:>POKE 50:0 1          ; Disable PrintScreen function
        C:>POKE 40:4 3E8        ; Install COM3 BIOS address
        C:>POKE 40:78 2         ; Change LPT1 timeout
