/dev/port is _very_ danegrous to use, especially if you have older hardware
installed in your System. Once upon a time I hat a SCSI host adaptor
(Always IN2000) which works fine so far... But after accessing the parport's
DATA port through /dev/port, fsck found uncleanly unmounted partitions...
Looking at the kernel's implementation for /dev/port, I saw that _all_ ports
up to that one you may have askey for get read. I even saw other systems
simply crashing by this. ...but unfortunately, you can't seek within a
character device with any other method than reading everythink up to the
requested position;(
