If I remember right the settings reported by : >stty -a < /decom0 were reasonable (done on the console). : >Regards - Tibor Sashegyi (cproto@cs.curtin.edu.au) : 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. : Regards - Tibor Sashegyi (cproto@cs.curtin.edu.au)
