Small tweak to cope with using barcode scanners via remote c9 where barcode is configured to transmit STX.

In point of sale screen the barcode would misread as '42' instead of actual barcode. This version includes a temporary fix that makes such scanners work.

One subtle variation between remote and local STX programmed barcodes is remotely for now , barcode scanner will behave as though it wasn't programmed. You'll need to manually key in qty sold in point of sale for example.
