That guy asked the scalar vendor to add this command and the command works as expected. But there is already a command in the Dell AIO scalar UART command spec. which can do the same thing since 2015, and the newly introduced get_scalar_status command is undocumented. To prevent from introducing regression in the future and to align with what Windows uses, replace this command with get_display_mode command. [Fix] Replace get_scalar_status command with get_display_mode command. [Test] Verified on new Dell AIO platforms. [Regression Potential] Low, the command is already in the spec. since 2015.
