: The settings are _almost_ reasonable but I just noticed that
: the setting becomes "a bit strange". After login the setting
^^^^^^^^^^^^^^^^^^^^^^^
: is 8N1. Once I start VI/ELVIS it becomes 7N1. My first terminal
^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
: goes doesn't have 7N1 and throws up in a bad way. The second
bad luck, probably not a lot you can do about it
: junk terminal can be set to 7N1 and works happily with this
: setting. It's a bit inconvenient though to enter setup before
: and after an edit session.
Exactly my point - vi, more, and I think less all fiddle with the
stty and when you exit, the settings are 7E1 when your terminal is
8N1. I think, from memory (quite some time ago), that more garbled
the stty as soon as you ran it, I may be wrong. Have a look on minnie
and grab the archives for c.o.3.* for the last two months or so. The
discussion became fairly technical and I among many others probably
skimmed without really understanding what the details were. I seem to
remember there was some talk of hacking the tty driver to provide an
8 bit clean environment. I don't know how far this has gone.
