The answer to that question is ABSOLUTELY!!! Many servers, including ours, will
revert to the "older less efficient" Telnet character mode and do the 3270
conversion on the server.  This reduces the capacity of the network
significantly and the server will have more work to do, but servers do support
the capability.  Note: Some servers don't, too!  So, it is really at the
server as to what it does if a Client will not run in 3270 mode.
