is there any possibility to get information to system through another port as keyboard port.

e.g. we would like to get information through a barcode scanner into Dataease software. Is it possible?

Most Barcode readers use the Keyboard buffer to get the data into the application.

We have ?"millions"? of application that use a simple USB Barcode reader that basically just read the result into the active field via the keyboard buffer.

The challenge whit this of course is if you are using a form with many fields as it would read it into any field as long as that field is the one that is active.

The alternative is to use a driver that activates the reader and await the read.

To do this you would need to use a CDF or something like that that communicate with the driver.

A CDF is quite straightforward to make if one is skilled in c/c++ programming.
