Selecting the LTS when loading the RealPort driver shows an extra two ports. Example, the LTS 32 will show 34 for the default.
Example below is regarding the Windows RealPort driver.
Port 33 = Built-in modem (ttyS0 internally on the LTS)
Port 34 = Xbee (ttyS1 internally on the LTS)
The internal modem and Xbee are available on the LTS "W" models only.
