Thanks!!! I took your code and put it in the OnComm Event method and tried to scan a bar code. I changed the comments to wait windows so I see what the values are returning. Every time I scanned the bar code it came back with commevent = 3 (Change in the CTS line.). It never returns a commevent = 2.

I am adding the input value to a form property and then parse the data left of a chr(13).

Any ideas?

>>I am using the MSComm object to receive data from a bar code scanner. I need to be able receive different lengths of data from 21 to 185 characters. I also need to know what the CommEvent values mean. Any ideas?
