Group, Looked in the archives about setting the serial cables to DCE. I've set the jumpers on the MCI card to 41 and 51. I also experimented with taking the one jumper on the applique off but I still can't seem to get it to pick up the DCE side. So I have two questions? 1. Can the older V.35 34 pin applique be set to DCE? 2. Can I use the CAB-v35mt cable which would usually be plugged from a dsu to the hd60 on the 2500. Or is there a difference in the pin outs? Thanks in advance for all advice.
