    No; ppdev isn't supposed to be some stealth version of /dev/port. If dosemu
    and Wine want to provide enhanced port services, they will need to trap the
    I/O accesses and emulate the requested operation at a higher level. I don't
    imagine there will be all that much call for this, though - DOS programs
    probably won't care about ECP all that much, and Windows ones should be going
    via some kind of device driver anyway.
