AuxOutPtr                Pointer to AUX: Output Driver

 AuxOutPtr                                                               [TP]

    Turbo Pascal supports the predefined device AUX:, both as a filename
    and as a predefined file variable. Output to this device is handled
    through the procedure AuxOut(Ch : Char), which simply makes MS-DOS
    system call 4. You can declare your own procedure AuxOut, then assign
    its address to AuxOutPtr; this makes your function the new output
    driver for the AUX: device.
