PointoPoint link between two Ninotnc`s

Today I am playing with tncattach, I thought it would be fun to test this with the Ninotnc`s.

I have connect the first Ninotnc n9600A4 to my rpi 4 and install “tncattach” on it. The TNCs are connected with each other by means of a short cable.  Cross cable. The tnc are running 9600Baud

TNC1             TNC2
RX                   TX
TX                   RX

# If you don't already have a compiler installed
sudo apt install build-essential

# Clone repository from GitHub
git clone https://github.com/markqvist/tncattach.git

# Move into source directory
cd tncattach

# Make program

# Install to system
sudo make install

The next thing I did was setting up a pointopoint link. But first attach the modem.

sudo tncattach /dev/ttyACM0 57600 -d --noipv6 --noup --mtu 329
sudo ifconfig tnc0 pointopoint

The second Ninotnc n9600A3 I have connected to my rpi 3

sudo tncattach /dev/ttyACM0 57600 -d --noipv6 --noup --mtu 329 
sudo ifconfig tnc0 pointopoint

I made a short video of how it works.

That was Fun….
