_PARALLEL_CHIP_MODE structure

Description

The PARALLEL_CHIP_MODE structure specifies the operating mode of a parallel port.

Members

ModeFlags

Specifies an operating mode of a parallel port, either an enhanced parallel port (EPP) mode or an extended capabilities port (ECP) mode.

success

Not used.

Syntax

typedef struct _PARALLEL_CHIP_MODE {
  UCHAR   ModeFlags;
  BOOLEAN success;
} PARALLEL_CHIP_MODE, *PPARALLEL_CHIP_MODE;

Remarks

A client uses a PARALLEL_CHIP_MODE structure with internal device control requests to set and clear the operating mode of a parallel port.

Note Microsoft does not recommend using a client-supplied interrupt routine. The use of interrupts might cause system instability. By default, the IOCTL_INTERNAL_PARALLEL_CONNECT_INTERRUPT request is disabled. For more information, see Connecting an Interrupt Service Routine to a ParallelPort.
