NAME
    CMD_FLUSH - Aborts all inprogress and queued requests

SYNOPSIS
    Standard device command.

FUNCTION
    Aborts all inprogress and queued speech requests.

INPUTS
    Valid IORequest block with the io_Command field set to CMD_FLUSH.
    A valid IORequest block is one with its io_Message structure, and
    io_Device and io_Unit fields properly initialized.  The easiest
    way to insure proper initialization is to make a copy of the
    IORequest block after a successful OpenDevice call.

RESULTS
    io_Error in IORequest block set to 0
