Unable to open COMx

Error and Warning Messages > Unable to open COMx

This error is reported when the Temprecord program is unable to initialize the COM Port to communicate with the logger.  The message will indicate which COM port (COM1, COM2, COM3 or COM4) it was attempting to use. This could be because:

•the COM Port does not exist on your computer.

•the COM Port is in use by another application.

Select Options/COM Port to investigate which COM Ports are available.  The Options/COM Port screen displays for each of COM1 to COM4, whether the port is in use by another application, in use by Temprecord, or non-existent.  You must choose a COM Port that is not in use and is fitted to your computer.

Other devices which also use COM Ports are a mouse and a modem.
