P3 at 115,200 baud

Richard Fjeld
I can't find it now, but someone posted something showing a screen capture with the latest P3 f/w and Utility running at 115,200 baud rate.  

I'd like to know how they got the K3 to go that high?  Mine tops out at 38,400 using 4.39 f/w.

I'd rather be learning.

Re: [KX3] P3 at 115,200 baud

The link between PC and P3  can now be 4800, 9600, 19200, 38400, 57600, or 15200 if your hardware is good enough. The link between P3 and K3 remains 38400. The K3 is not likely to change this. This was done for P3 image transfer.

When commands and responses are short, turnaround time is dominant and the link speed just doesn't make all that much difference.

They didn't and likely won't, everyone's K3 maxes out at 38Kbps.  The
115Kbps is P3->PC only to improve the screen capture process.  Not all
PC serial ports [real or simulated] will work at that speed however.
