NAME
    Reset -- reinitializes the parallel device

FUNCTION
    This command resets the parallel device to its freshly initialized
    condition. It aborts all I/O requests both queued and current and
    sets the devices's flags and parameters to their boot-up time
    default values. At boot-up time the PTermArray is random, and it
    will be so also here.

IO REQUEST
    io_Message      mn_ReplyPort initialized
    io_Device       set by opendevice
    io_Unit         set by opendevice
    io_Command      CMD_RESET (01)

RESULTS
    Error -- if the Reset succeded, then io_Error will be null.
             if the Reset failed, then the io_Error will be non-zero.
