▶ Serial Port Console Redirection
▶ Console Redirection
Console Redirection operates in host systems that do not have a monitor and
keyboard attached. This setting enables/disables the operation of console
redirection. When set to [Enabled], BIOS redirects and sends all contents that
should be displayed on the screen to the serial COM port for display on the
terminal screen. Besides, all data received from the serial port is interpreted as
keystrokes from a local keyboard.
