SC100 Smalltalk Screen Interface

Question

Hi (also published on the VWNC list),
We are considering options for interacting with an outdated Unix system. One option we would like to explore is screening the VT100 terminal session.

Is there anything to support the terminals of the Smalltalk VT100 terminal, for example, VA old EHLLAPI 3270 interface? (It worked well for me in the Reuters FX / VA / AS400 system back in '95).

There wasn’t much luck searching, except for some very old references to CTermConnection in VW 2.5 and Ian Piumarta VT102Emulator for Squeak since 2002.
This is a standalone Seaside app, so any Smalltalk dialect will do.

Thanks for any help,
Bob

Answer 1

Smallalk / X includes VT52 and VT100 emulators. They are not perfect and do not emulate the entire set of escape sequences, but even if they are incomplete, they can provide something to begin with (and extract material that processes escape sequences). ST / X can submit files to the standard junk e-mail format (or extract source code from another cvs repository)

However, if you are running on the coast, I think you better look for the javascript vt100 emulator and write a shell widget for it on the coast (which simply breaks through key events and incoming data). In the end, there may be less work, as I believe there are many JS emulators.
