Console problem (with apologies)

[BIKEMAN]

My apologies for those who have seen this a few times... I haven't had much luck getting it posted so though I'd try it one last time. No more after this. Promise.   Hi all   I have two 2nd hand 2501's that are giving me a few headaches - when I plug the console cable into the console port I can see the output but the routers don't seem to accept any input. The cable and laptop are fine since I use the combination on a number of other routers without any problems.   Any ideas ?   Thanks   Rudi
