rs485.py/sys/devices/platform/msm_serial_hsl.0/rs_mode
which will return either RS232 or RS485.
rs485.py/sys/devices/platform/msm_serial_hsl.0/rs485_term <NEW
MODE>
Where <NEW MODE> is either:
· 0—RS-485 termination resistor is disabled (drives GPIO63 high; the termination
resistor is active low) (default)
· 1—RS-485 termination resistor is enabled (drives GPIO63 low)
For example, to enable the RS-485 termination resistor: rs485.py/sys/devices/
platform/msm_serial_hsl.0/rs485_term 1
rs485.py/sys/devices/platform/msm_serial_hsl.0/rs485_term
which will return either DISABLED or ENABLED.
