    Subjectserial console problems under 2.4.4/5
    From
    Date
    Hi. I have started having serial console problems in the last bunch of
    kernel releases. I have tried various 2.4.4 and 2.4.5 ac kernels (up
    to and including 2.4.5-ac4) and the problem has persisted. The problem
    is basically that serial console doesn't recieve. I know that the
    hardware works properly, and lilo and other kernels even work fine
    from serial console. As far as I can tell, only one direction is
    broken, serial receive. (ie, an echo foo > /dev/ttyS0 shows up on
    the serial console, but an echo to the serial device on the other end
    of the console never shows up)

    The serial hardware is detected:
    Serial driver version 5.05b (2001-05-03) with MANY_PORTS SHARE_IRQ SERIAL_PCI enabled
    ttyS00 at 0x03f8 (irq = 4) is a 16550A
    ttyS01 at 0x02f8 (irq = 3) is a 16550A

    the pertinant parts of .config are:
    CONFIG_SERIAL=y
    CONFIG_SERIAL_CONSOLE=y
    # CONFIG_SERIAL_EXTENDED is not set
    CONFIG_SERIAL_NONSTANDARD=y
    # CONFIG_COMPUTONE is not set
    CONFIG_ROCKETPORT=y
    # CONFIG_CYCLADES is not set

    Has anyone else seen this, or have any ideas what is broken?
    thanks...
