Nuttx Shell prompt not accepting commands when used via screen

Hello,

Configuration of my drone-
Multicopter UAV: PX4 is running on Pixhawk v2 hardware.

Scenario:

  1. I have logged in into nuttx console via screen on Ubuntu Machine.
  2. nsh> prompt flahes.
  3. A lot of info, warn logging messages keep coming on console and does not allow to enter commands on prompt.

Is there any command or key combination to get nsh prompt ready for accepting commands?
