Figure 2. Advanced Settings of COM port
Port speed and related parameters have no practical effect on USB serial devices, so you can leave
the defaults for these parameters.
After changing the COM port number, you need eject the Device from the USB port and insert it back. Until
doing this, applications may fail to open the Device’s port.
2. Other Microsoft Windows versions
Open the “Device Manager” in the “Computer Management” applet of the Control Panel. If the Device
appears in the “Other devices” section after connection and has a yellow notification sign, then you need
to install a driver. You need only the .INF file (no code installation is required) which will link the Device
with the standard USBSER.SYS driver of Microsoft Windows.
