Try these steps:
Disable Bluetooth Insert dtoverlay=pi3-disable-bt into /boot/config.txt
Disable hciuart systemctl disable hciuart
Disable serial getty systemctl disable serial-getty@...
Reboot Raspberry Pi systemctl reboot
When Pi is back on, try running the pitnc programs as root or use sudo

Hello,
A few years ago I installed a BBS on a Raspberry with a TNC-Pi2. Unfortunatly my SD card died recently and I had to re-install all.
I follow the last version of the documentation available on but I'm not able to get "pitnc_getparams"? working (Raspberry Pi3 B).
- I installed Raspbian Stretch (2019-04-08-raspbian-stretch-lite.img)
- I set the Serial port as mentioned (serial login shell disable/serial interface enable).
- Then I downloaded the the pitnc_get/set_param binaries, made them executable and launch "./pitnc_getparams /dev/serial0 0"? but it is constantly "retrying..." .
- Just in case I tried with ttyAMA0 but it is not better...
I also tried to follow the note mentioned in the documentation "Note added 12/4/2018" but it is not working better, I even try with Raspbian version with the GUI, still the same...
Now I don't know where to search to troubleshoot the issue, if you have some advices to guide me, they are welcome :-)
Thank you
