I have 2 - USB to Serial Adapters on Win XP. I had one software setup to use with one adapter and after adding the second adapter and telling the second software which port to use the first piece of software will not communicate with it’s device. The error I get states that COM2 is being used by another device. In the device manager each one has been set up on a separate COM port.
Does anyone know how to get these devices to work together? Both adapters are “plugable” brand from Amazon. !](https://d2r1vs3d9006ap.cloudfront.net/s3_images/905538/photo_inline.JPG?1369747207)](https://d2r1vs3d9006ap.cloudfront.net/s3_images/905538/photo.JPG?1369747207)
