I wanted to have a look at what the Z3805A puts out on Port 2.

I can see the LEDS flickering on the BOB so its saying something.
I connected up a terminal program set to 96008N1 and it seems there is nothing.
So I plugged the cable into port one to check the settings:
scpi > syst:comm:ser2:pace?
NONE
scpi > syst:comm:ser2:baud?
+9600
scpi > syst:comm:ser2:parity?
NONE
scpi > syst:comm:ser2:bits?
+8
scpi > syst:comm:ser2:sbits?
+1
So Serial 2 is definitely 96008N1.

Nothing displays on the terminal program so I used a serial port monitor program and I see this recurring data:

01 03 00 09 04 01 04 02 08 02 06 01 06 00 00 0D
01 03 00 09 04 01 04 02 08 02 08 01 06 00 00 0D
01 03 00 09 04 01 04 02 08 03 00 01 06 00 00 0D
01 03 00 09 04 01 04 02 08 03 02 01 06 00 00 0D
01 03 00 09 04 01 04 02 08 03 04 01 06 00 00 0D
01 03 00 09 04 01 04 02 08 03 06 01 06 00 00 0D
01 03 00 09 04 01 04 02 08 03 08 01 06 00 00 0D
01 03 00 09 04 01 04 02 08 04 00 01 06 00 00 0D
01 03 00 09 04 01 04 02 08 04 02 01 06 00 00 0D
01 03 00 09 04 01 04 02 08 04 04 01 06 00 00 0D

I can see its transmitting the even second time but what format is this and how can I use it?
