  • nonblock [on|off|numsecs]


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.
