System: Ubuntu 16.04 LTS Browser: Firefox plugin version: downloaded from bin/Linux_x86_64/npjUART.so at commit 979c040 Test process: Have an Arduino board constantly sending data to serial port connected to computer. With the following code, the data will be displayed to the console. However, if the device is disconnected and reconnected, calling ser.is_open() will return true, but no message can be received anymore
