Serial

1. Custom
   • Type: plist dict
   • Description: Update serial port properties in BaseSerialPortLib16550. This section lists the PCD values that are used by the BaseSerialPortLib16550. When option Override is set to false, this dictionary is optional.
2. Init
   • Type: plist boolean
   • Failsafe: false
   • Description: Perform serial port initialisation.

   This option will perform serial port initialisation within OpenCore prior to enabling (any) debug logging. Refer to the Debugging section for details.

3. Override
   • Type: plist boolean
   • Failsafe: false
   • Description: Override serial port properties. When this option is set to false, no keys from Custom will be overridden. This option will override serial port properties listed in the Serial Custom Properties section below.
