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.

Configuring iDRAC to use SOL using RACADM
To configure IPMI Serial over LAN (SOL):
1. Enable IPMI Serial over LAN using the command.
racadm set iDRAC.IPMISol.Enable 1
