/** @file
Serial I/O port control interface extension.
This library provides an extension to the library providing common
serial I/O port functions that is defined in MdePkg. The aim is to
provide more control over the functionalities of a serial port. The
extension covers all the needs of the UEFI Serial I/O Protocol.
Though, its use is not restricted to the UEFI Serial I/O Protocol.
It could for example be used in the PEI phase of the boot sequence
as well.
