[nfbcs] Honeywell VIP 7813 terminal emulator?

Fri Sep 2 17:02:11 UTC 2011

Steve's reply covers all the bases I was thinking about.  Thanks Steve
for taking the time to write this up.

The UNIX GUI that Steve mentioned is called X11, and is almost
certainly not a factor here since the program is running in a
terminal.

Leslie, to summarize Steve's email a bit, here are two questions
you should try and research the answers to.

  1) Can this database be accessed using a windows program or a web browser?

  2) Is the database application hard coded to use Honeywell terminal
     codes, or does it use a technology such as "curses" to control
     the terminal.

If the database uses something like curses, then you aren't tied to
the Honeywell terminal. This is good, because I'm sure we can
recommend terminal emulators that work well with Jaws, but probably
don't emulate something as obscure as the Honeywell terminal.

Steve is also correct that you may well need some scripting to
efficiently use the terminal based program.

Hope this helps,

Jim
