The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

IBM does not have scripting built-in to their Telnet program.
I have done scripting in the following ways (each an alternative -- no
need to do all):
1) Using a 3rd party telnet client, such as one of the open source ones
for Linux together with the Expect tool.
2) Writing a proxy that observes the Telnet data stream and inserts
data... allowing the user to watch while the "script" (really a proxy)
controls the action.
3) Using the Virtual Terminal APIs (this is very advanced programming
-- requires in-depth knowledge of the 5250 data stream.)
4) Using the EHLLAPI technique -- you rarely see this anymore -- but
essentially allows a Windows program to take control of your 5250
emulator. The emulator can then run the TELNET command, etc.
So it's certainly possible, but not necessarily easy. Telnet is really
designed for interactive use -- and while it's certainly possible to
programmatically control it, even after getting past the problem of the
"plumbing" (i.e. one the options above) the result isn't always that
satisfactory, since applications aren't really designed for programmatic
access.
As such I'd think long and hard about whether there's a better way
before falling back to scripting a telnet session.

Can you do something like this with TELNET?
