PARALLEL_CHIP_MODE structure (parallel.h)
The PARALLEL_CHIP_MODE structure specifies the operating mode of a parallel port.
Syntax
typedef struct _PARALLEL_CHIP_MODE {
UCHAR ModeFlags;
BOOLEAN success;
} PARALLEL_CHIP_MODE, *PPARALLEL_CHIP_MODE;
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.
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.
