Re: TTY display trouble

[Richard M. Stallman]

    Yes, in place of the termcap:ti string emacs apparently outputs now,
    which selects the "Alternate Screen Buffer" with the side effect of
    excluding emacs screens from the terminal scroll back buffer.

How come the ti string doesn't solve the problem?
Is it because Screen doesn't support the alternate screen buffer?
In that case, perhaps Emacs should output the newlines only
when there is no ti capability.

    PS: EMACS uses the alt screen when I enable it in GNU SCREEN
    although TCONV reports no such capability, I'm baffled.

How about if you put a breakpoint at set_terminal_modes
and see what happens?
