I am looking to use /dev/port to access the parallel (printer) port.
This because ioperm does not read port addresses above 0x3ff and I want
to use my PCI printer port at 0xd800.
The explanations I have seen seemed to indicate the port and the lseek's
origin to be identical (doesn't work). Haven't found a satisfactory
example to model. Can someone explain how to use /dev/port using lseek
and read?
