I installed lineage os 14 on raspberry pi 3 I connected a gps module with UART port, however, the baud rate of GPS is 9600 but baud rate of /dev/ttyS0 is 115200 I want to change the baud rate of ttyS0 in order to read GPS data I tried stty command
stty -F /dev/ttyS0 9600
However, this won't change the baud rate when I check again with this command
stty -F /dev/ttyS0 the speed value is 115200.
How can I change the baud rate of /dev/ttyS0 I also find some solution with serial command
serial /dev/ttyS0 9600 however it doesn't exist on adb shell.Any help would be grateful
