What is "5250" protocol
#201

I had someone ask me about a "5250" protocol the other day and I have
been unable to find any reference to it.

Any pointers to where I might find out something about it would be greatly
appreciated.  A brief description would be great too.

5250 is an IBM terminal / controller system.  It is similar to the much
more common 3270 series (but the underlying protocol is different).  For
one thing, a 5250 terminal is usually connected to it's controller via a
twinax cable, whereas 3270 uses coax.  I think that 5250 is real common on
IBM's midrange systems.  

If you want to find info on it, consult the IBM KWIC (Key Work In Context) 
reference for a list of 5250 manuals.

It's the terminal protocol for IBM System/3X minicomputers, in the
same way that 3270 is the terminal protocol for mainframes.  I believe
the AS/400 supports both, though.

5250 is the code number for the display protocol used by AS/400s (and
System 36, 38 etc...). As you're a VM'er, I suggest you ask your local
IBM rep for the number of a manual which will describe the protocol
in detail.
