    Hello,

    The MPC8360 have :
    _ two RS232 ports .
    _ two RS485 ports.

    I would like to use the second serial port with a cable connected to J3 connector.
    The first RS232 runs but I have nothing on the the second serial port.

    When I make this command :
    echo test /dev/ttyS0 I obtain Test.
    echo test /dev/ttyS1 I obtain nothing, I think, it's the RS485 port.
    echo test /dev/ttyS2 I obtain Cannot create /dev/ttyS2, no such device or driver
    echo test /dev/ttyS3 I obtain Cannot create /dev/ttyS3, no such device or driver

    Thank you for your help.
