Re: Usage Of Com 1

Hi all,

I've completed developing my system with Delphi 7, then, I began to realise that the users are not able to scan with the 2D Barcode scanner which is being hooked up to Com 1.

What should I do? Is there any extra coding required for this? If there are, how should I do it? Are there any third-party components that I can use to solve this problem?

Please advice.

   Do you receive something from COM1 at all ... ? Is the barcode hook properly installed ?

There is a response from COM1 but the only thing is that, it doesn't display anything on the edit box. Could it be that I need to install a component to enable it to read from COM Ports?

The 2D barcode scanner is hooked properly.

I've tried hooking up a 1D barcode scanner at the Serial Port (sharing the same port as the keyboard) and it works fine.

What could the problem be?

   I think your hook is somehow not working with 2D

Which port is your 2D barcode hooked up on?

Do you add in any special components or extra coding to help you to capture the values from the 2D barcode if hooked on COM 1?

   I am using it on COM2. With the reader I was given a DLL hook. I had to register it with regsvr32...
