Bring lpt.{c,h} from -CURRENT.  These files are esentually the same as the
previous nlpt.{c,h}.  MAJOR history was lost when nlpt.{c,h} -> lpt.{c,h}
in -CURRENT as these files weren't repository copied.  So for the record:

Major ppbus commit with:

        + ECP parallel port chipset FIFO detection
        + DMA+FIFO parallel I/O handled as chipset specific
        + nlpt updated in order to use the above enhanced parallel I/O.
          Use 'lptcontrol -e' to use enhanced I/O
        + Various options documented in LINT
        + Full IEEE1284 NIBBLE and BYTE modes support. See ppbus(4) for
          an overview of the IEEE1284 standard
        + Detection of PnP parallel devices at boot
        + Read capability added to nlpt driver to get IEEE1284 compliant
          printer status with a simple 'cat /dev/lpt0'
        + IEEE1284 peripheral emulation added to BYTE mode. Two computers
          may dialog according to IEEE1284 signaling method.
          See PERIPH_1284 option and /sys/dev/ppbus/ppi.c

All this code is supposed to provide basic functions for IEEE1284 programming.
ppi.c and lpt.c may act as examples.
