So Microsoft do not mention that you need to add something to the app manifest for serial communication nor is there a tick box in the app manifest GUI for serial communication.
The following needs to be added to your app manifest (create the <Capabilities>
section if it doesn‘t exist):
<Capabilities>
<DeviceCapability Name="serialcommunication">
<Device Id="any">
<Function Type="name:serialPort" />
</Device>
</DeviceCapability>
</Capabilities>
UPDATE 10/2016
Microsoft have updated their documentation to reflect this requirement.
