Reply To: USB-RS232 scale indicator on Pi: permission error, ttyUSB0/ttyUSB1 changing, readline hanging

Translated from Türkçe by AI ·

The permission problem is gone after adding the user to dialout, thanks. But I have two new issues: after rebooting the Pi, sometimes the scale indicator becomes ttyUSB1 (there is also a USB-RS485 on the same Pi), and readline sometimes waits forever, with nothing being printed. The indicator data does flow in a terminal program, though.
