exec-timeout 30 0

transport input all
transport output none

Try port 8 with a straight-thru cable and ensure you clear the line
before you attempt the reverse telnet

Did that; cleared the line, then I tried on async 8.!

this is killing me.
And all these Con0's work with a straight thru console session and a pc
(with hyperterm, and SecureCRT) and I have tried through the 2511
console, through telnet through the console, and telnet from my desktop
through to the 2511 and then reverse telnet from those connections too!

Hello! Glad nobody has given up yet! it did not change a thing... you
have a as2511rj? what do you have on your Con0's on the other routers?
Any security settings or anything?

Also, can I check the health of these ports (async ports?)

I did the research and got the latest non buggy for the 2511 series,
here is the sh ver:

(Anything I am missing?)

inout ; cannot hurt at this point

Given that you know the various router console ports are good and your
cables are good, the only thing not provend yet is whetehr the 2511
async ports are good.

You could try setting up Windows to the server port testing using the
following Cisco doc:

The issue, Layer 1 of course!

2 rollovers from cisco (light blue) - the flat blue rollovers that I
had they must have not been made coorectly OR the cables relied on the
db9 "snap-in" connectors to make it a true rollover. I could not tell
by looking at thee nds of them if they were correct rollovers. . So I
made a plenum cat6 (all I had) rollover on my own and it worked like a
champ!! With No configs on the receiving Con0 and only "no exec" and
"preferred telnet" under lines 1 16 on the 2511. On thing is for sure
My humble advice:
Building your own lab brings you all kinds of "accidental" knowledge.
Unbelievable, painful, but good solid learning. I know now more than I
ever wanted about async's and rollovers and 2511's!
A big Thank you.
