hello, I have two ACB-IV sync cards on different PCs.on suse linux 6.2 system, I installed the drivers and configured the hdlc0 interfaces on both machines.I want to make a connection between them.but I couldn't succeed so far. As I have 2 ports and two interfaces (hdlc0 and hdlc1), I can not get sure which port belongs to which interface. what kind of cable should I use? all resources available are for windows systems.are there any others for linux? ece. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
