Hello, I've had a problem using GnuEmacs 18.55 (?) for some time. What happens is I lose characters from my screen. They are still there but I can't see them anymore. ^L rewrites the screen and they are back. This generally happens when I insert or delete a character into the middle of a line or just traverse over some existing characters. At school using a Wyse 75 terminal things work great but at 2400 baud, Procomm+, and vt100 this problem is a tremendous headache. Any ideas as to a fix. Anything will be appreciated. Thanks, Jeff Sandfort sandfort@cs.arizona.edu

Thanks, Sounds like your terminal type is set incorrectly. Specifically, it sounds like Emacs thinks you are on a terminal that can insert characters in the middle of the line, which the VT100 cannot do. It is sending the "enter insert mode" escape sequence and then sending the inserted characters, but the emulator correctly ignores the escape sequence and the characters just overwrite what was there. Make sure that you set your Unix terminal type to "vt100" when you login from the modem. -- Barry Margolin, Thinking Machines Corp. barmar@think.com {uunet,harvard}!think!barmar

We've had this problem with both emacs and nuTPU. It turns out that both are sensitive to tab settings. Use the SETUP key on the terminal and set the tabs to the default, every 8 positions. The nuTPU folks confirmed this sensitivity after we found it through luck.
