-/** @file\r
- Console Splitter Driver. Any Handle that attatched console I/O protocols\r
- (Console In device, Console Out device, Console Error device, Simple Pointer\r
- protocol, Absolute Pointer protocol) can be bound by this driver.\r
-\r
- So far it works like any other driver by opening a SimpleTextIn and/or\r
- SimpleTextOut protocol with EFI_OPEN_PROTOCOL_BY_DRIVER attributes. The big\r
- difference is this driver does not layer a protocol on the passed in\r
- handle, or construct a child handle like a standard device or bus driver.\r
- This driver produces three virtual handles as children, one for console input\r
- splitter, one for console output splitter and one for error output splitter.\r
- These 3 virtual handles would be installed on gST.\r
-\r
- Each virtual handle, that supports the Console I/O protocol, will be produced\r
- in the driver entry point. The virtual handle are added on driver entry and\r
- never removed. Such design ensures sytem function well during none console\r
- device situation.\r
