I'm having problems with the "s4" and "7300" terminfo/termcap entries
on our 3B1's and 3B15. Some of our users like to dial from one machine
to another using the Telephone Manager in UNIX PC mode, rather than
have it emulate a vt100 or a 513 terminal. Unfortunately, there
appears to be a problem in the terminal emulation and/or in its
interaction with termcap/terminfo in this mode. Specifically, vi gets
very confused about what line it is on, in a manner that suggests
scrolling and/or wordwrap problems.
I've called the hotline and been told (after 20 or 30 minutes of
insistence) that there is a "problem" (which I already knew) and not to
use UNIX PC mode. Does anyone know whether the problem is in the
terminal emulation itself, or just in the termcap/terminfo entries? If
the latter is true, does anyone have a fix? Thanks.
(We're running 3.50, if it makes a difference.)

The problem is that the automatic margins feature is broken in terminal emulation (async_main) from the phone manager. This has been broken for some time. At one time I had an async_main with this fixed from Jonathon Clarke, but that was for 3.0 and no one supports the fix in 3.5 or 3.51. The fix got "lost" by the developers. As a work-around you can take /etc/termcap and edit out the :am: option. Also go to the terminfo database and infocmp -> vi -> tic the s4 entry. Warning this will affect local use as well as dial-in use. Joe Wood lznv!jlw

Hmm, I've noticed this at the *console* too if I'm using a non-standard sized font in slot 0. I know they say you're not supposed to put a smaller font than 9x12 into slot 0, but if you don't you can't get a cursor smaller than 9x12. The small fonts seem to work, and vi sort of works, but ^D mungs the screen terribly. I'd also be most interested if anybody has a fix for this. -- Jim Rosenberg CIS: 71515,124 decvax!idis! \ WELL: jer allegra! ---- pitt!amanue!jr BIX: jrosenberg uunet!cmcl2!cadre! /

The phone manager is so absurdly slow I'm always amazed to hear that anyone is actually using it. If the machine you're dialing into is a unix box then set it up with a copy of the unixpc termcap and things will work just fine. If you must have vt100 emulation then I think you're just out of luck until someone fixes the phone manager or writes a decent replacement. But if you must have vt100 emulation then you're probably dialing into the wrong kind of computer anyway. :-) -- Richard Foulk ...{vortex,ihnp4}!islenet!richard Honolulu, Hawaii
