[Xastir] Tinytrak TNC not opening interface

Mon Feb 8 09:11:52 PST 2021

That code looks familiar for some reason...

Look at xastir/src/util.c

Based on the /dev/cu comment, I guess it hangs because of blocking(?). I don't believe there is a permission on that port. I can apply a generic username (guest) in putty with the autologin username without problem.

When I run PuTTY on the /dev/tty.usbserial-1430 port I can see packets coming in from a test transmitter. I close putty and open xastir so the port isn't blocking. When I go to start the TNC interface, in mac it hangs without messages in the terminal window. On the putty it doesn't hang but there's nothing. There are never incoming packets from the view data window. Unfortunately, Byonics say they don't know much about xastir. I've tried this both on my mac and my raspberry. The cable setup works for programming and PuTTY, so I don't think its that or drivers. I think it comes down to settings. Is there anything I can try?
