There are definite bugs in the Macterminal 0.5X vt100 handling, enough
that it is very difficult to use with Tops20 EMACS - it tends to leave
old garbage on the screen while moving around in the file. After
some playing around I've determined that the problem is that
Clear-to-end-of-screen ([J) and Clear-to-end-of-line ([K)
do not work if there is data in the mac's input buffer. To test it try
writing a program the repeatedly outputs something like

[H[J

A good part of the time (depending on the system load) it will
leave the screen blank except for the top line (which will be
the @i(2nd) line of the text that was on the screen).

I suspect that your changing the termcap entry to 'ovt100'
invoked more padding and got around the bug.

While I'm beating on Macterminal there are also a few features
I don't like.

o to get a you have to type BS (or some other
keys). This is inconvenient on a Tops20 when you have to
use delete alot (and backspace rarely). There should be
some way to switch the meanings of BS and BS.

o You can't save the state of 'Record lines off top'

o There are no arrow keys. The 'option-mouse' almost works,
except when you're in something like the TV editor which
keeps the terminal cursor at the bottom of the screen
at all times.

o The 'option-mouse' function makes no attempt to optimize the
cursor keys, in fact it usually takes the worst possible
path, to move down one line in the same column it moves
back to column 0, THEN goes down, and forward to the right
column.


(This is the version of Macterminal dated July 12,1984. Admittedly
it's a Beta test, hopefully these will be fixed by the real release.)
