This structure stores the type of error and the communication status. Executing IOCTL_SERIAL_GET_COMMSTATUS populates this structure.

Syntax

typedef struct _SERIAL_DEV_STATUS {
  DWORD Errors;
  COMSTAT ComStat;
} SERIAL_DEV_STATUS, *PSERIAL_DEV_STATUS;

Errors
Bitmask containing the types of errors.

The following table shows this bitmask.

Bit	Description
CE_BREAK	Hardware detected a break condition.
CE_FRAME	Hardware detected a framing error.
