Don,

If your RED LED power light is flashing, your power supply is very weak.  It needs to be steady on all the time.  If adding an external USB device like a TNC-X causes it to start flashing, then again, the power supply is too weak.

that's one of the first syntaxes I used. The yellow light is flashing on the Pi Hat. All of the lights blink when power is applied.

Putting it to bed for a while. If I plugged my USB tnc-x I get it to start in not type.

I've been reading the setup from tncpi pdf from off the tnc-x website.

I've downloaded the zipped files,  there are now in the folder pitnc.

Both files permission are for Owner 

I keep getting retrying.

If I do ls /dev/serial*

It shows /dev/serial0 and /dev/serial1

So sort of lost as to where to go next
