NOTE: BIOS sends the screen serial data in 25 x 80 format. The SSH window that is used to invoke the
console
com2
command must be set to 25 x 80. Then, the redirected screen appears correctly.
NOTE: If the boot loader or operating system provides serial redirection such as GRUB or Linux, then the BIOS
Redirection After Boot setting must be disabled. This is to avoid potential race condition of multiple components
accessing the serial port.
