P3 baud rates

[N5GE]

I can't find the installation instructions for the P3SVGA on the web site.

I installed the latest firmware and utility for the P3 last night and noticed
that the utility now tries to start with two new baud rates before settling at
38400.

Where can I find an explanation of the use of the new available baud rates for
the P3?  I saw a post last night where these new baud rates were referred to, so
I'd like to know how to use them please.

Try the P3 "RS-232" menu selection and the firmware release notes file
available from the P3 Utility Help menu describes the new firmware version
changes.

The new firmware version and P3 Utility add two new speeds, 57,600 and
115,200 bps. The P3 Utility tries all the baud rates and settles on the one
it gets responses for, as it always has.

115,200 may be a bit dicey for image transfers and it doesn't work at all
for firmware load.  

I can't transfer images at 115,200 bps reliably here. Others are having
difficulty transferring a full image.  Consider 115,200 "experimental" for
now, we're debating its value.

Firmware load for the SVGA and FPGA may occur at 38400 or 57600 bps.  If the
P3 is set to 57600 before starting firmware load, the P3 MCU is loaded at
38400 bps and the SVGA and FPGA are loaded at 57,600 bps.  It's a little
faster, but not a lot faster.  115,200 isn't working for firmware load, so
the P3 Utility doesn't even try.

At the moment, the P3 can use these higher baud rates to more quickly
send bitmap screen captures to the host computer.  The link between P3
and K3 maxes out at 38400 though.
