Send and Receive data from scanner

[kaka21]

Hi Roman,
I bought nrcomm Lib v6.65 several years ago. But still couldn't figure it out how to use it.
I've a machine called Opscan OMR Scanner (NCS Pearson) with rs232. OpScan is a specialized scanner designed to grade placement tests, bypass tests, regular tests, student surveys and other bubble sheets. I'm trying to make a project to send and receive data from that scanner.
I've tried the demo project Demos\DTerminal to send command and it works, the scanner start scanning the bubble sheet.
For receive data from the scanner, I also tried demo project Demos\Codes and it reads the data but in hex. What I want to know is how to read the real data of bubble sheet? Is it possible with nrcomm library?

Thanks :)
