/** @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.

Assert or deassert the control signals on a serial port.

. Request to Send

. EFI_SERIAL_REQUEST_TO_SEND : assert/deassert the
"Request To Send" control signal if this bit is
equal to one/zero.
. EFI_SERIAL_DATA_TERMINAL_READY : assert/deassert
the "Data Terminal Ready" control signal if this
bit is equal to one/zero.
. EFI_SERIAL_HARDWARE_LOOPBACK_ENABLE : enable/disable
the hardware loopback if this bit is equal to
one/zero.
. EFI_SERIAL_SOFTWARE_LOOPBACK_ENABLE : not supported.
. EFI_SERIAL_HARDWARE_FLOW_CONTROL_ENABLE : enable/
disable the hardware flow control based on CTS (Clear
To Send) and RTS (Ready To Send) control signals.
@retval RETURN_SUCCESS The new control bits were set on the serial device.
@retval RETURN_UNSUPPORTED The serial device does not support this operation.
