I had questions about how to configure a Cisco 2511 to use as a console
server for Sparcs.
Thanks to:

I attach John Heasley's posting, as it included an ASCII version of the
mod adapters I needed to construct, not only for the Sparcs but also for
lots of other serial devices, like router consoles.
Once the cabling and the Cisco box is in place, one telnets to the IP
address of the Cisco 2511 ... specifying a high port number as follows:
"telnet cisco 2001" would give you port 1, "telnet cisco 2002" would be
port 2, and so on.
I now have a Cisco 2511 acting as a console server, and I can happily
telnet to the serial consoles of my Sparc stacks. Thank you for the
responses,
