I see what you're after now. yes you can do this. the adapters are the trick here.
cisco will use a rollover cable to essentially pair wire 1 on one end to wire 8 on the other end (2 to 7, 3 to 6, etc...). in theory what this does is reverses the the Tx and the Rx and the other corresponding wires for flow control and modem control. the adapter then comes in for when you plug it in to the interface. for example if I have a eia-232 configuration, then my adapter will have to be wired correctly to place the correct pin from the adapter to the correct wire on the rollover cable. same thing can be said if I have a v.35 cable, I need to have the adapter connect the Tx pin to the Tx wire of the cable. this is why cisco advertises their db-60 interface as being 5-in-1, because depending on how the pins match the wire, they have 5 different specifications possible(one being eia-232) now sticking to eia-232, the specification calls for 8 pins, which is perfect for 8-wire cable and thus why cisco uses it for all their modular console ports. now the adapters come into play. the adapters can serve one of two purposes, 1) straight-through or 2)rollover. if the cable you use is a rollover, well then the wires have already turned the Tx into a Rx wire and thus your adapter needs to be straight-through to accomplish having the ends stay Tx to Rx. if the cable you use is straight, well then the wires are Tx to Tx and thus you'll need an adapter to change the Tx to the Rx. now heres the kicker and the reason I suspect you're having problems. this whole discussion of Tx going to a Rx end-to-end depends on the fact that the console port of a router (or a CSS) is a DTE and your PC serial port is a DTE and thus needs to be rolled-over. on the other hand some older cisco equipment had their console ports configured as DCEs, which might very well be you case. so what to do? put the adapter onto your computers serial port, plug the cisco rollover cable into it and then right into the console port of your css. if it works you're done, if not get a standard straight-through cat5 cable to use instead of the cisco rollover, that one will then work.
