Gary, Hello...
You statement that the scanner needs to be independent of where the user is in the GUI does not make sense to me, so can you explain what you are trying to achieve? We have done quite a bit of scanner work using USB/Wedge readers, RS-232 readers, and IP based readers via web services. Each is unique in how it works, and has specific implications on how you develop your software. Maybe you can elaborate a bit more on what you are trying to achieve by using bar code readers?

Hi Tony and others, Interesting that this subject should come up now, we're also looking at adding barcode reading to our software. Our application needs to be independent of where the user is in the GUI and we're looking at low resource settings so we need to stay away from IP scanners if we can. Which I guess leaves us with RS232 or serial emulation via USB with appropriate driver. We're in a Windows environment so GET SERIAL PORT MAPPING isn't so useful for us I think. Anyone got any pointers on how to identify the correct port to use with SET CHANNEL (I assume this is the way we have to go) and general advice with getting this working?
