SERIALPERF_STATS structure (ntddser.h)
The SERIALPERF_STATS structure contains performance statistics for a serial port.
Syntax
typedef struct _SERIALPERF_STATS {
ULONG ReceivedCount;
ULONG TransmittedCount;
ULONG FrameErrorCount;
ULONG SerialOverrunErrorCount;
ULONG BufferOverrunErrorCount;
ULONG ParityErrorCount;
} SERIALPERF_STATS, *PSERIALPERF_STATS;
Members
ReceivedCount
The number of characters received since either the serial port was opened or the last IOCTL_SERIAL_CLEAR_STATS request was processed.
TransmittedCount
The number of characters transmitted since either the serial port was opened or the last IOCTL_SERIAL_CLEAR_STATS request was processed.
FrameErrorCount
The number of frame errors detected since either the serial port was opened or the last IOCTL_SERIAL_CLEAR_STATS request was processed.
SerialOverrunErrorCount
The number of serial overrun errors detected since either the serial port was opened or the last IOCTL_SERIAL_CLEAR_STATS request was processed.
BufferOverrunErrorCount
The number of buffer overrun errors detected since either the serial port was opened or the last IOCTL_SERIAL_CLEAR_STATS request was processed.
ParityErrorCount
The number of parity errors detected since either the serial port was opened or the last IOCTL_SERIAL_CLEAR_STATS request was processed.
Remarks
This structure is used by the IOCTL_SERIAL_GET_STATS request.
To reset the performance statistics to zero, send an IOCTL_SERIAL_CLEAR_STATS request.
