In which case I hope you don't mind too much that I spent another weekend
hacking on telnet and terminals...
For anyone who might find it useful, there's a new version here:

and a new screenshot to go with it:

The telnet stuff should now work on Mac and Windows too (assuming they
implement Socket>>setOption:value: correctly) but please let me know
if you try it on these platforms, since I haven't.
I tweaked performance in TtyMorph a little: it now runs at 20% the speed
of the real xterm. It also comes with its own font now, infinitely nicer
than Atlanta.
Oh yes, I also added support for "connecting" to a pseudo tty. IOW,
it now supports talking to a local interactive shell (that thinks it's
connected to a real terminal [which it is, although the terminal is
being emulated entirely in Squeak ;-] and so will work just like any
login shell should: job control, window tcset/getattr work properly
[so Emacs, less and friends will happily run], etc, etc...).
For the shell to work you need AsynchFilePlugin support and the (brand
new) PseudoTTYPlugin. (It just so happens they're bundled in the new
3.2-3 Unix VMs. ;)
Hope you like it. Enjoy!
Ian
PS: The PTYPlugin should work with any OS that provides Unix98-compliant
ptys (I've tested it on GNU and Solaris). Cygwin has them, but plain
Windows almost certainly doesn't. (MacOS [version 9 and earlier]
hasn't a rat's chance. ;)
PPS: If there's a real interest in this stuff then I could be persuaded
to add some pages to a swiki explaining it all.
