[Elecraft] Elecraft K3 utility - RS-232 port speed?

[rrkrr]

I have downloaded the Elecraft K3 utility and have it running on my
Ubuntu computer.  The utility communicates with the K3 and sees the
firmware version I presently have as 2.7.  Right now the serial port
speed on my computer is 9600 baud.  However, I can't find a recommended
port speed to use for the firmware upgrade in the K3 utility
documentation.  Can someone clue me in?
