A level converter designed to work with EIA232 ports won't work on a parallel port. They are different beasts with different voltage levels and pin-outs. In any case: as far as I know, Hamlib does not supports rig control via a parallel port. > Both run the same Debian Sarge > release with very similar sets of software packages.

The specific error in the message log is: > "ppdev0: claim the port first" Check that the parport is enabled in the BIOS of your laptop, and that it is set to bi-directional instead of the old legacy unidirectional mode, if you plan to use it as such. Make sure the ppdev module is loaded: su -c lsmod | grep ppdev It looks like it is. Then make sure no other userland applications ( cwdaemon, line printing, zip drives etc etc) have laid claim over the parport. The Hamlib packages on Debian Sarge work well - even the Perl bindings are there. Hope this helps.
