    If you have downloaded this script file, remove
    any captured communications header and then enter
        DEBUG < filename
    where filename is the name of this script file.
Here is an interrupt call that seems to work under DESQview, Windows, and 
OS/2, and doesn't appear to be harmful under plain MS-DOS, either:
reg 1, &h1680
call interrupt &h2F
