***SOLVED*** Apparently you cannot have more than one client with the port open at same time? once other client closed serial port my new client on Win10 worked just fine.***
Cannot open serial port with application on Windows 10. I can get the com port to open if I select "Always grant port open requests" but then it just says cannot acquire... I am using latest driver for Win10 and I can connect to the Digione SP via TCP/IP. The device manager does show the com port is "connected". I also tried using a serial terminal and does same thing... can get to open port but stuck on acquiring. Also this DigiOne SP works from different PC running Win7 with issues so I don't think it is a DigiOne SP issue unless I need to update the firmware. This is located at a remote site so I dont want to risk putting it offline... just trying to set up a new PC with Win10 to replace old PC. Any ideas?
