patch 9.1.0321: Garbled output on serial terminals with XON/XOFF flow control Commit: https://github.com/vim/vim/commit/49528da8a60f8fd38ca491d6ccec47dfccf5f23c Author: Anton Sharonov <anton.sharonov@gmail.com> Date: Sun Apr 14 20:02:24 2024 +0200 patch 9.1.0321: Garbled output on serial terminals with XON/XOFF flow control 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 Signed-off-by: Anton Sharonov <anton.sharonov@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
