But the thing that brings this to the foreground in my
thoughts is that today I had to troubleshoot a 3174-51R at a
customer's site. This thing is connected, via a rather
unusual cable, to a Cisco 2500 series router, so that means
the 25 pin connector on the back must be some form of X.25 or
something like that. I know that the fellow at corestore.org
has been able to get a real IBM terminal to telnet into an
emulated system via a terminal controller with built in
ethernet (although I have never seen one).
This is usually SDLC that is source-route-bridged over IP. S390 Open
System Adapters (or whatever they called the ethernet/ip adapters for
old S390's) could talk SRB/IP. It's been 13 years since I played with
these.
So, on the "cluster controller" (3174) end you have stock SDLC via
synchronous serial on either RS232 or V.35. On the server end you'll
need to get hercules to emulate an OSA.
