===== Default Keybindings =====

None.

===== Syntax =====

  * ''**nonblock** [on|off|//numsecs//]''

===== Description =====

Tell ''screen'' how to deal with user interfaces (displays) that cease to
accept output.  This can happen if a user presses ''^S'' or a TCP/modem
connection gets cut but no hangup is received.  If ''nonblock'' is off
(this is the default) ''screen'' waits until the display restarts to
accept the output.  If ''nonblock'' is on, ''screen'' waits until the
timeout is reached (on is treated as a one second timeout). If the display
still doesn't receive characters, screen will consider it "blocked" and
stop sending characters to it.  If at some time it resumes accepting
characters, screen will unblock the display and redisplay the updated
window contents.
