We would like to connect ASCII terminals across a public data network
(e.g. Telenet) to a 3270 emulator (7171) connected to our large IBM
systems. There are a few problems here: We want to echo locally to the
terminal (at the remote PAD, i.e. far from the host) most of the time,
in order to minimize the number of packets being sent across the PDN;
we plan on packetizing on control characters, and whenever the user
types <esc> plus a sequence of characters (to allow for emulation of PF
keys, etc.). I'm not sure about the other PDNs, but with Telenet at
least there are X.29 parameters to set it up this way. The problem is
that we think the 7171 will *always* echo *everything* it hears,
including what the remote PAD is *already* echoing to the terminal.
It looks like what we were hoping to do won't work. Has anyone used
IBM systems in this way (ascii terminals connected with no special
software across a PDN to a 3270 emulation box)? If so, how did you do
it?
