This file contains information on know problems, bugs, and misfeatures of
|
|
supdup, as well as any other random pieces of information that need to
|
|
be somewhere.
|
|
|
|
SUPDUPD needs a new /bin/login because the standard login trashes the
|
|
environment. The /bin/login that we use is included. The only
|
|
requirement is that the TERMCAP (and TERMINFO if you're using it) gets
|
|
passed through as well as the TERM environment variable.
|
|
|
|
The server should do the same optimization with character insert and
|
|
delete that it does with line insert and delete.
|
|
|
|
I probably should make use of scroll regions. But this is a pain.
|
|
|
|
If TTYLOC is defined, then the SUPDUP location feature uses Romkey's
|
|
ttyloc code. This could easily be replaced by whatever your
|
|
particular machine does about tty location, or left out all together
|
|
of course. The user supdup doesn't yet send TTYLOC information.
|
|
|
|
The banner should tell you to turn off overstrike if necessary.
|
|
|
|
3600's have this bug where if you position the cursor at the beginning
|
|
of the line and do a newline, the first character of the line is erased.
|
|
I have programmed around this bug to some extent, but it sometimes
|
|
reappears. They also have a bug that if you type a meta character the
|
|
character that gets sent is shifted and if you type meta shift character
|
|
it sends a lowercase character. There is nothing I can do about this.
|
|
|
|
For some reason talk, amoung a few other things, core dumps when
|
|
supduping in from a lisp machine (either a 3600 or a cadr). I've seen
|
|
the same bug a BBN bitgraph. It seems to be a bug with programs which
|
|
use curses and is evoked by large screen sizes.
