I can ifconfig the two machines and I've enabled debugging in the lpt.c module. When I try to ping a machine, it does actaully send every byte but viewing the lines using a logic analyser shows that the handshaking lines sit (for the most part) at one level and only occasionally flip. (I know they should alternate if things are working okay). The remote machine replies (with what I don't know) and this is received back at the originating machine as a long list made up of 0x6x [reconstituted] bytes. Same results in either direction. I've set both parallel ports to "SPP" mode and I've tried using another machine (a Compaq Proliant) in various combinations to no avail. I soldered up another cable with no joy either. Can anyone offer any more help in this direction? Logic analyser traces available on request!
