[Elecraft] computer - P3 - K3 communications blues

[Alan Bloom]

It may be a baud rate issue.  You can change the baud rate of the 
PC-to-PC link in a MENU entry in the P3 called "RS232".

Note that changing the baud rate of the K3 doesn't do anything when the 
P3 is connected.  The P3 will change it right back to 38400.  The baud 
rate that the computer sees is the one that is set in the P3 menu.
