I have a Rock 3A and a Rock 3C panel i enabled on both the uart2 which is /dev/ttyS2, and i tested both with usb ttl stick with windows pc and they worked properly, but i have a device which using modbus protocol for communication and it is work well on Rock 3A but not working with Rock 3C, is there some difference in uart2 in 3A/3C clock speed or something else what can cause this problem?
