Fix serial port permission denied errors on Linux April 8, 2013 Linux Jesin A 28 Comments The ancient serial port which is no longer found on the latest motherboards and even the not so latest laptops is still used for connecting to the console of networking devices, headless computers and a lot other applications. This made the IDE work correctly, but I lost the ability to use the correct serial port. In the dev folder, the port I need is listed as permission 166. Someone (who is no longer in the area to help me) swapped the permissions to 666, which made it all work gloriously. You could try. Sudo chmod 666 /dev/ttyACM0 Which will give you read/write permissions for the serial port in question. Import serial. Of course, this is not the best way to go, it would be better to try setting different permissions on the device itself, like. Sudo chmod 777 /dev/ttyACM0 or (for exclusive access to the user pi) sudo chown pi:pi /dev/ttyACM0 or similar. You can get some more information here. Error opening serial port /dev/ttyacm0. permission denied. ![]() Equitrac Professional helps law offices gain control over cost recovery and document expenses, providing firms with comprehensive print management software and document capture capabilities that reduce costs, increase security and eliminate waste. 2002-2012 Nuance Communications, Inc.
