[comp.emacs] debugging GNU Emacs 18.54

dwp@mtune.ATT.COM (David Preisler) (10/25/89)

On a 3b2 700 under sVr3 I've got GNU Emacs 18.54 built [ HAVE_PTY defined ],
but I find that it does not work properly through a DataKit VC.  I do find
however, that when run through a direct port it appears to work properly.

Symptoms:  The screen opens up correctly, but typed chars do not appear on 
the screen.  Ctrl chars are also generally ignored.  Emacs will beep at ^g 
and ^z, and occasionally it will produce the unsupported operation message 
( autosave, abort- core dump ).

Does anyone know what is going on or [ even ] how to debug the problem.


thanks again,

I had the same problem with GNU Emacs over STARLAN. One question, are the
devices DataKit use for remote logins streamio devices? If they are you're
out of luck. When I found out that STARLAN devices were streamio devices, I
was annoyed. When I found out that streamio devices do not behave like
tty's, I was ticked. GNU Emacs makes certain ioctl calls that will fail on
streamio devices. I could'nt find a solution to my problem.
