I will go back to the manual and look at this again. But I will tell you up front that I have been trying to configure conserver to use the RFC-2217 protocol and I am getting the login prompts. I have assumed this request to authenticate was coming from the Opengear.

i just took a quick look at pages 45 through 49 of that CM4000 user manual. i'd suggest setting the access type to "Raw TCP" and having conserver connect on ports 4000+n. the rfc 2217 stuff doesn't seem right for conserver purposes (conserver certainly doesn't talk it so there might be some weirdness there). the implication (based on the manual) is that there won't be a login prompt using raw tcp.

there's my 2 cents.
The RFC-2217 protocol does not authenticate and it will be Telnet compatible where as you may experience TTY corruption using raw TCP. Sredird which we use to serve RFC-2217 should handle all the Telnet escape sequences more appropriately.

I just verified that the latest firmware 2.3.1u3 is behaving correctly when using RFC-2217 on port 1 with my Linux telnet client:

# telnet 5001

If you could send through your Support Report or at least the configuration section to support@opengear.com (perhaps take this offline while we sort out the problem) I can try and work out if there is a configuration issue.
