Well, found out I've got another problem. I recently upgraded my laptop computer. It has no Serial port. So I purchased a USB to Serial converter. It has worked fine on 4 of the products that I carry that uses serial connections. However, I tried connecting to a TSU2000 today and ProntoEdit says "There are no COM ports installed on your machine." The USB adapter is installed on COM 2. Anybody else had problems with this? Thanks.
