Re: PiTNC9k6 settings

So everything works great via I2C. Radio is hooked up, tones all sound good, other stations can see me. When receiving, I see the ADC auto adjusts, and drops from 200 to an actual of 127. Amber rx light comes on, but I get nothing back in to xastir.
I have tried a few Packet terminals I have found, but they all want actual d\serial or ax.25 ports to talk and will not recognize the symlink created using the i2ckiss program. I have looked at the schematic, and it appears the original pitnc9k6 used RX1 and TX1 on the teensy (Serial 1) at pins 0 and 1.
Tracing from the Pi serial pins (8 & 10 on the 40 pin header) they run thru the 2 jumpers to pins 7&8 on the Teensy (RX3 and TX3).
In TeensyConfigPacket.h, it is configured as serial1. I changed that to serial3, and still no comm to the teensy via serial.
Has anyone actually been able to use the PiTNC9k6 with serial/AX.25 at all, and if so, how? I have gone thru my pi settings, even hooked up an FTDI cable and re-configured the serial port as a console port to verify it is working as it should.
And the 2 jumper blocks are on the 2 end pins of each 3 pin header closest to the end of the board (Rpi GPIO Pin 1 end) and both have continuity from the pi to the teensy.

I am testing version 11 to make sure everything is working before I start loading it on new TNC's. I have noted that the default values are not being set on the Teensy when I first flash it. This is what I get on the console.
