Protocol Interface Structure
typedef struct {
EFI_DEBUGPORT_RESET Reset;
EFI_DEBUGPORT_WRITE Write;
EFI_DEBUGPORT_READ Read;
EFI_DEBUGPORT_POLL Poll;
} EFI_DEBUGPORT_PROTOCOL;
Parameters
Reset Resets the debugport hardware.
Write Send a buffer of characters to the debugport device.
Read Receive a buffer of characters from the debugport device.
Poll Determine if there is any data available to be read from the
debugport device.
Description
The Debugport protocol is used for byte stream communication with a debugport device. The
debugport can be a standard UART Serial port, a USB-based character device, or potentially any
character-based I/O device.
The attributes for all UART-style debugport device interfaces are defined in the DEBUGPORT
variable (see Section 16.3.3).
