VT102 codes

[Adam Wiggins]

Ah-ha!  Found it.  Just mounted the stupid thing under linux (forgot how
easy that is).

Here it is - if you've got any questions feel free to ask but it's really
very straightforward.  I coded in all the stuff we have right now in
a couple hours one night, and that was counting that I had to give myself
a quick refresher course on how all our low level IO/socket stuff worked.
