[WT-support] Speed jumps up occasionally

[Bob Wilson, N6TV]

I assume you use a lot of "+++" and "---" in your scripts?  Which WinKey
chip version are you using?  (Win-Test reports WK Version detected it at
start-up at the bottom of the logging window).

The last time I looked at a WinKey communications log, which you can produce
using the microHAM Router [SET] button next to the Winkey port, I saw that
Win-Test can sometimes issue [Cancel Buffered Speed Change] commands (1E)
between every letter sent.

According to a private note from K1EL, copied to Oliver and Laurent last
January:

"All the buffered speed cancels are troubling, the application should keep
track of speed changes and only issue commands when they are really
warranted. While WKUSB is able to handle them it chews up a ton of CPU
bandwidth to constantly invoke all the math calls that are required."

So there could indeed be a problem with the way Win-Test is sending commands
to the WinKey.

BTW, using "+++" and "---" will usually make it somewhat harder for CW
Skimmers to figure out your code speed and your callsign.  I've decided not
to use them any more and I've had no issues with WinKey speed jumps.
