For loading the Teensy, go to the old Pi-TNC site and look at the manual for the PiTNC-9k6 there.? It has instructions for compiling and loading

I use Putty as SSH as well as VNC ¨C which is why I was sort of curious why turning off Secure Shell seemed to work as I didn¡¯t connect that way.? Unless it reserved it somehow?

I got my 9k6 from WVC ARC via Etsy.? I saw the Coastal site.? That is where (I believe) I go the ¡®manual¡¯ to follow that was the TNC-Pi originally.? I did find a link I had stuck away (and forgotten) to a ¡®manual¡¯ to assemble the WVC board.? That had some additional information in it as well.? That was here:

And your PiGate site was the genesis of my intent to get packet working in my Go Kit ?? Easy and smooth operation with my V71A to a WinLink node was appealing ¨C but there were NO TNC boards except the 9K6 available.? And since the V71A can do 9600 I said WTH ¨C another arrow in the quiver in addition to standard 1200.

My hang up at the moment is the WVC manual which states (implies?) that the Teensy board needs to be loaded with software.? I need to read and digest that a little bit to figure out what that means.? But at the moment all I have ¡°loaded¡± directly is the Pi itself.? I did see later in this string (or earlier in time) about the AX25 files and I have to go see if those are on the board or not.?
?
It will be steps but as long as I know the steps I should be OK overall.? The challenge to me is finding and understanding the steps ?

When you connect through PuTTY, is is through an SSH or Secure Shell TCP/IP connection port, not serial.? VNC is also through a direct connection at a non-serial port.
Where did you get the TNC-Pi9k6 from?? I've attached the docs from the old Coastal Chipworks site.? The board and procedure to build it is a little different than the other people selling this board, but the firmware configuration docs are still correct.
I'm getting ready to make a change in my website to reflect that the TNC-Pi9k6 is the choice for both the PiGate and PiGate RMS devices.? Is is a drop-in replacement for the TNC-Pi2.? I'm not too happy with the progress MFJ is making with building the new TNC-Pi3 board, and the West Virginia group that is now selling the TNC-Pi9k6 as an assembled board has a great price, which is probably going to be close to what MFJ sells the 1200 baud only board for.
Here's my web site in case you are interested in using your Pi and the TNC for communications with Winlink2000.

So after six tries because it is early and I simply can¡¯t type (and I have learned Linux is very unforgiving on typing!) I got the following:

Using Serial Port /dev/serial0?
retrying
?
and a presentation of the parameters.??

Now at least I know they are talking to each other ?

I am not sure why it worked but it did.? I am going to presume that somehow the putty connection to the pi was using the serial port?? Although how it still connects (as does VNC) confuses me ¨C but no matter.

The obvious next question is where do I go from here for reading about how to configure and use this board?

First, you'll also need to use the raspi-config utility to enable the console serial port, but disable console login.
Then go to menu 5, Interfacing Options, then menu P6, and disable the login shell over the serial port.
On the next screen, keep the serial port enabled.
Now try "sudo pitnc-getparams /dev/serial0 0"
This works the same with the TNC-Pi2 or the TNC-Pi9k6 and will be the same with the TNC-Pi3 once MFJ starts selling them.

Having said that I purchased a TNC9k6 and have it running wiht a Raspberry PI 3B+.? Followed directions at (downloaded the pitnc files, set them in the directory and set permission to execute by owner.? Verified with ls -l that all permissions and owner/group ids as well as my logge din user are all setup per the text.
when I run the ./pitnc_getparams /dev/serial0 0 - I get the notation that RPi is using Serial 0 then Com Open Failed: permission denied.
I'm at a loss.? Searching here provides a slew of comm errors dated years back that are not trying serial but? ./pitnc_getparams 0 0 - when I try that it defaults to a TTY device (AAM0?) and simply repeats "retrying" which purportedly means a configuration issue.? But what configuration it is straight out of the setup - I've tweaked nothing in the RPI configuration.
Help?
