[comp.sys.apollo] vt100 emulation on SR10.1?

gsg0384@uxa.cso.uiuc.edu (08/23/89)

Hi,

Is there any decent vt100 or xterm emulation software beside the vt100
that comes with SR10.1?  The latter is really a lemon.  Is there any patch
program available for vt100?

I will appreciate any information.

A while ago I had a simple terminal emulator posted to comp.sources.misc,
and have since improved it to include most of the features I suggested
could be added in the original. It is not vt100 or xterm compatible, but it
is more than sufficient for vn, nethack, more, less and just about everything
I have tested it with (there is, as I just discovered, a bug with vi).

I will submit the new improved version to comp.sources.misc soon.

If anybody is curious about the nature of the vt100bug, it lies in the
insistance by vt100 to use /dev/ttypa and /dev/ptypa, and not to try any
others if it fails. The correct thing to do is to start with ptyp0 and
move through to ptypf until one is found which is unoccupied.

The error comes about when ptypa has, for some reason, had its modes changed
so that it can't be opened, or has been opened by a different process.
I consider his particular bug to be outright sloppy programming rather than
a bug per se.
