I have a new CR3003 compact USB Cash Drawer because the new computers doesn't have serial port. The cash drawer is already configured like you can see in the picture. I need help to understand why it's doesn't work. Serial cash drawer with real port work good but now look like cobol can't communicate appropriately using USB cable HID to Virtual COM Port.

The Cash Drawer open good using that program, but from rmcobol program doesn't work, ignore.

This is the windows configuration port.

Wascar, I did a search to find the manual.  My interpretation of the manual is that the codes you enter using the programming utility are binary, not ASCII.  So, change the COBOL program to:

        MOVE X"00000000" TO COM-TEST.

Remove the DISPLAY.

Hope this fixes it.

Thank you very much Tom. It is the second time in a few years that you help me with the same theme. Your answer is correct. I get the idea that you should write a book on cobol where you show with examples all your knowledge for the future and the new generations. Thank you so much.
