I recently received a free copy of Comfort View V3.0 software (Hear that Trane Management, free) due to that fact we will be servicing a new building with that system in it. I loaded the software no problem in my laptop and went about my business. The next day I was at a Trane job and needed to access a PCM. Couldn’t do it, my comm. port was taken over by the Carrier software. I uninstalled the Carrier stuff and continued on my way. I am now back at the office and have reloaded the Comfort View. I am trying to find a way to release the comm. port manually and re-initializing it when I need to. Does anyone know if and how to do this?
