-  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.

-

-  @param  BaudRate         The requested baud rate. A BaudRate value of 0 will 
use the the
-                           device's default interface speed.
-  @param  ReceiveFifoDepth The requested depth of the FIFO on the receive side 
of the
-                           serial interface. A ReceiveFifoDepth value of 0 
will use
-                           the device's default FIFO depth.

device's default time
-                           out value.
-  @param  Parity           The type of parity to use on this serial device. A 
Parity value of
-                           DefaultParity will use the device's default parity 
value.
-  @param  DataBits         The number of data bits to use on the serial 
device. A DataBits
-                           value of 0 will use the device's default data bit 
setting.
-  @param  StopBits         The number of stop bits to use on this serial 
device. A StopBits
-                           value of DefaultStopBits will use the device's 
default number of
