A quick glance at the opticon.c code looks like it is a driver which only gives generic serial port like access to the scanner (makes life of a programmer simple by not having to work with USB). You will have to ask for the protocol from the manufacturer to talk to the device to collect the bar codes stored in the flash memory. Some manufacturers might not give it (Of course they will have free windows software and drivers for it) . For an other manufacturer I had to sign a NDA and fax it to the USA before they gave me the protocol for a DAQ device...
