Hi, I can not get the serial usb to work on the EPIC.
Using the USB port 0, it appears in the Manage-> System-> Serial Devices as / dev / ttySer0 and Port Number 0. I have tried:
1- With pac control 10 and a comm handle “ser: 0, …”, the OpenOutgoingCommunication command returns a -49 (nobody else is using it)
2- Node-Red with the strategy stopped and the node-red-node-serialport configured as /dev/ttySer0 or /dev/ttyUSB0 returns a Permission Denied error, can not open /dev/ttySer0
The device I am using has worked on linux, windows, mac …
