Return Value:
Considerations:
Supported in the DOS API library and the Windows NT API library
Example:
HANDLE Handle;
int retcode;
retcode = OC_ResetScanner( Handle, OCWAIT );
ATTENTION
!
This call stops scanning and resets outputs.
Parameter: Description:
handle Must be a valid handle returned from OC_OpenScanner
mode If mode is:
OCNOWAIT OC_ResetScanner returns after releasing the
reset signal to the scanner.
OCWAIT OC_ResetScanner returns after POST is completed.
OCSOFTRESET OC_ResetScanner reinitializes while avoiding the
7-second POST delay. In this mode, the scanner performs
a warm-boot and bypasses the POST. The dual-port RAM
can be epartitioned quickly.
The scanner stops scanning, resets all outputs, and
returns to the power-on condition. After the reset is
complete, you must call OC_InitScanner to initialize the
shared memory interface.
