[Elecraft] P3 - Commands don't work

[Fred Jensen]

My P3 seems to work perfectly ... except it doesn't respond to commands 
I send using the Command Tester in the P3 Utility.  If past experience 
is any indicator, this is a pilot-problem.  The P3 says it's connected 
to the computer at 38400.  Commands to the K3 [thru the P3] work fine 
and I can download the BMP image from the P3 fine.  I just downloaded 
the latest production FW for the K3 and P3.

When I send "=" it returns "P3"

When I send "#SPN000500;" it returns nothing and the span does not go to 
50 KHz

No other command that I've tried has done anything.

I might be misreading the P3 Programmers Manual but it appears that all 
commands have the syntax: #<command><data>;  and the P3 Utility sends 
the command when I type the semicolon.  I've had the P3 for a number of 
years but have never tried to command it from the Utility.
