Epson PX-4 bar code reader software

Epson bar code wand H00BR

This package from Pocket Computers LTD, came on a tape with the Epson H00BR bar code wand. Lacking any documentation I haven't got it working yet on my PX-4. Some disassembly of the BCR.COM file suggests it installs itself in User-BIOS. It is then called from the Basic program. The wand itself is probably just a HP QEDS-1099 and a button. The zip file contains three programs:

BCR.COM - the driver which loads itself into high memory.
BCRDEM22.BAS - A Basic demo program, which utilizes the BCR.COM driver and decodes several types of bar code.
BCRDEM.BAS - Equal to BCRDEM22.BAS but without comment, making it about 2 kByte smaller.

Also available, a preliminary disassembled BCR.COM
