patch 9.1.0321: Garbled output on serial terminals with XON/XOFF flow controlv9.1.0321
Problem: When used terminal with XON/XOFF flow control, vim tries to
still make CTRL-S mapping available, which results in severe
screen corruption, especially on large redraws, and even
spurious inputs (John Tsiombikas)
Solution: Disallow CTRL-S mapping if such terminal is recognized.
Don't remove IXON from the bitmask inversion.
(Anton Sharonov)
*** When started like this:
TERM=vt420 vim
:set termcap
shows "t_xon=y"
map <C-S> :echo "abc"<CR>
does nothing (after <C-S> output freezes and subsequent <C-Q>
unfreezes it)
*** When started like this:
TERM=xterm vim
:set termcap
shows "t_xon="
map <C-S> :echo "abc"<CR>
works (after <C-S> one see "abc" string echo-ed)
fixes: #12674
closes: #14542
