I’ve got several port servers running serial devices, and have a loop to establish connections to each of the devices. It now appears that if I don’t have IP connection to the digi TS II (16 port) that the open call hangs when we open the tty port. It doesn’t return an error message (which I’d expect it to do).
Is this a known behavior? I would not have expected this.
I believe I’m using the most current drivers (1.9), and am running Linux ES3 (update 7).
