This is a most strange problem, which I only get it using GNU Screen

  • 0

This is a most strange problem, which I only get it using GNU Screen and a Nokia N900. Under vi (both vim and nvi, it turns out) if I type in insert mode one<Enter>two I get

Mtwo
one

So, not only does <Enter> put an M at the beginning of the line, but actually it does something pretty weird in the meantime. Among other things, this issue doesn’t let me save and exit.

Any thoughts? Thanks in advance.

POSSIBLE ANSWER: It turns out I wasn’t the only one having this issue, which is gone (at least in our case) by simply adding term xterm to your .screenrc. Sorry for not doing a more thorough search before asking…

    Your <Enter> is like a carriage return and linefeed (<CRLF>). That’s ASCII 10, followed by ASCII 13 (which is the CTRL-M you see). The screen, however, isn’t supporting it. Try to do:

    export TERM=vt100

    then run vi, etc or just

    TERM=vt100 vi

    which should fix the behavior (assuming you have vt100 terminal capabilities).
