Re: Terminal serial to host cable
No. I used a standard Category 5 patch cable. Thanks - I am aware of the pinout of the Cisco rollover cables. Further, during this investigation I was using an ohmmeter to check connections.

Re: Terminal serial to host cable
Hi, Did you use the "BLACK" Cisco cable? If so look at this. It has a roll over. 1,2,3,4,5,6,7,8 become 8,7,6,5,4,3,2,1 say using pins 3 & 6 for TXD RXD, 4 & 5 sig gnd, 2 and 6 for RTS, CTS or what ever you have a cross over in the cable.

Terminal serial to host cable
I recently connected my Cisco terminal setup (a laptop with a DB9-RJ45 adapter on Serial A) to a UNIX workstation with the gender adapters shown in the ASCII diagram below. I was surprised that it worked llike this because I expected a crossover of TX and RX, but when I pulled the adapters apart and followed the wires from end-to-end it appears there is no crossover. Pin numbers shown are those stamped on the connectors. Laptop Workstation DB9-RJ45RJ45-DB25 tx 2 6 ---straight---62 tx rx 3 3 ---through33 rx cable Shouldn't TX and RX cross over? Why does this work?
