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