[Elecraft] CAUTION Re: [K3] Eterlogic VSPE 0.80

[Bill W4ZV]

One caution about using VSPE courtesy of N8LP below.  Do not connect any
other programs when running K3Utility for firmware updates.  It's possible
that the firmware update files could be corrupted by other programs
attempting to access the K3 during the update process.  Larry does not even
allow LP-Bridge to access to the K3Utility to avoid any potential problems.

Re: [LP-PAN] Re: LP-Bridge and PowerSDR v0.92 alphas released

Hi Bill. I block the K3 Utility commands. There is a mention on the LPB
web page to not use K3 Utility. I don't think it's safe to flash
firmware with more than one program connected to the K3. VSPE is like
LP-Bridge with all filtering disabled (ie, all ports connected to the
serial port, and vice versa). I would not use Utility with VSPE unless
it's the only application connected to VSPE at the time.

There are many situations I found in my testing of several other port
sharing programs many months ago where I had problems with polling
commands colliding, and causing missed commands and ignored commands by
the K3. Also, if all commands are returned to all programs, any program
without an asynchronous event driven serial implementation will get very
confused by all the unanticipated traffic. LP-Bridge isolates the
responses so that a program wont see anything it didn't poll for unless
you check AI1 or AI2. This is generally done for programs which don't poll.
