Xflag is a signal used by the peripheral during negotiation to accept
or reject a negotiated mode. It's low to accept nibble mode, and high
to accept everything else.
You can use the parport IEEE 1284 implementation to negotiate with
extensibility requests by using (IEEE1284_EXT_LINK | mode) as the
requested mode for parport_negotiate.
Does that help?
