Bixolon Ethernet Interface Setup Utility

on Apr 18, 2008 at 14:49 UTC ( #681526=CUFP: print w/ replies, xml ) Need Help??

Spent about a day reverse engineering the Bixolon ethernet interface setup protocol, so I could have a utility available on *nix systems.

Written with help from dylan and another co-worker.

Comments/critiques welcome.
