The device is interfaced to a Centronics printer port with the help of a couple of additional parts (basically, a line driver and a voltage doubler to create the required Vcc). The program performs direct IO on the printer port, bypassing the kernel privilege mechanism by using /dev/io. If there is interest in the program, i'm willing to make it a "port". (NB: i'm not on freebsd-hardware.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
