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