I have started XFS implementation of SZZT Pinpad .I am facing an issue with the WFSOpen command Its giving an error “ – 14 “which is mentioned as WFS_ERR_HARDWARE_ERROR in the Manual. Please let us know if we are missing out on any parameter Value for the same .
Also we are unable to find the logical Name for SZZT Pinpad in the Manual . As of now we are using the same name which is been mentioned in the Registry
I've had recently this problem. In my case, it was due to the service provider not being found (more exactly, the SP implementation DLL). The reason behind, in my case, was that I was using a 64 bits Windows 7. In a 64bits SO, the registry localization is not in HKEY_LOCAL_MACHINE\SOFTWARE\XFS but in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\XFS BTW, the xfs setup puts a 64bitsregs.reg in C:\xfs (or the directory you selected to install the xfs in)
you can find your logical name or service name from below path for windows xp:
general: HKEY_LOCAL_MACHINE\SOFTWARE\"AtmVendor"\RSPServer\XFS
in my case: HKEY_LOCAL_MACHINE\SOFTWARE\BanqIT\RSPServer\XFS
