[Elecraft] K3 Firmware program and Virtual serial port

[Lyle Johnson]

Brian,

Depends entirely on the software between the virtual serial port 
presented to Utility and the physical port connected to the radio.

For example, I have a MicroHam interface box and it cannot be reliably 
used when performing a K3 firmware load because it attempts to interpret 
the data stream -- its serial port to the radio does not simply emulate 
a wire.

I also have a RigExpert interface box and it works perfectly with 
Utility -- it does not attempt to interpret the data stream.

LP Bridge is creating a "virtual K3" and passes data from its "virtual 
K3" to other applications to allow sharing of the state of the radio 
(frequency, for example) and as a result is interpreting elements of the 
data streams.  The firmware load data is thus incompatible with the 
intent of LP Bridge.

73,
