Starting from COM1 and changing to COM2, etc for each device. You can assign Ports to each device. I hope that this information helps.

Follow the instructions below to locate the port settings tab. Open Device Manager from the Control Panel. In Device Manager, locate Ports (COM & LPT). Right click on Communication port and select Properties. Select Port Settings Tab and click on advanced button. Open the list box to change the settings. Check if the issue is resolved.
