Current Delorme mapping applications use the native USB interface of
this Delorme GPS receiver directly. A virtual COM port emulator IS NOT
installed by default.
You have to download and install the optional driver that intercepts the
USB interface and creates the simulated COM port, from the Delorme
website, before non-Delorme applications can use this GPS.
Further, restating a fact that has been repeated many, many, times
before on this and other APRS-related lists:
USB-interfaced devices will ONLY WORK with a PC.
There is NO WAY to use a USB-interfaced GPS with other devices such as a
Kenwood D700 or TH-D7, Tiny Track, KPC3 TNC, etc. For these
hardware-based applications, you MUST have a serial-interfaced GPS device.
