Hmmm, I moved PIC #2 up in PIC #1 spot, and put in a new unit in PIC #2 spot.
PIC#1 can now disable transmitter at will, YAY! So that confirms that there's nothing on the breadboard interfering...
when you disable the transmitter how are you setting the tx pin
code ?
IT'S THE DARN PIC !
I swapped the coding between the 2 PICs, and PIC #1 now has a framing error every time it tries to disable the transmitter.

I'm going to swap it for another unit...
PIC #1:
TXSTA.5 = 1 ' TXEN: Transmit Enable bit
hserout [ "[1]" ]
while TXSTA.1 = 0 ' Check TRMT: Transmit Shift...
Yes, they'll definitely be tri-state.
Demon Yesterday, 22:56I decreased the pause to 300uSec so everything is in the window when zoomed in.
The 2 transmits are working just fine, with the framing error over on the right.

In post 8 the trace is showing that the analyzer is detecting a framing error being generated by the transmitter when it sends the ']' and disables TXEN.
The TX data line should never idle low......
It's an awesome project. I can almost see the light at the end of the tunnel. I've done unit tests of every component all the way up to interfacing with MS Flight Sim. I'm just not seeing why I...
Demon Yesterday, 22:22don't give up on yourself or sell yourself short !...... it is a good project :)

Re: Framing error if I disable transmitter after shift register is empty?
I'm not doing anything to it. Should I?
