and expand the ports only 2 "Rim virtual serial ports V2 com 5" and com 6 appear. If I rt click on properties, port settings, advanced, a list of com ports comes up. Com 7 through com 14 come up and say in use but no other info. How do you tell what each is used for? I'm heading back to Mazatlan in the morning so will be off the computer for a day or two. Thanks for your help here. Maybe I can actually learn something here!
