property DeviceName : string
Determines the device name used to open the serial port.
DeviceName is usually set indirectly by setting the ComNumber property.
When ComNumber is set, DeviceName automatically gets set to a platform-appropriate value based on the value set in ComNumber.
For example, a ComNumber of 2 would generate a DeviceName of '/dev/ttyS1' on the Linux platform or '\\.\COM2' for the Windows platform.
If a non-standard device name is required, DeviceName can be set to the non-standard value prior to setting the Open property to True.
