    This was a common problem for systems dependent on this particular
    chip architecture for XPG3 branding which continues with XPG4.

    This is documented as a Known Problem in the VSX release notes.
    The problem is hardware related, certain processors are unable to maintain
    high throughput speeds.
    Test Output
    ************************************************************************
    /tset/POSIX.os/devclass/cfsetospee/T.cfsetospee 2 Failed

    Test Description:
    If general terminal interface supported:
    For each of the baud rates B50, B75, B110, B134, B150, B200, B300,
    B600, B1200, B1800, B2400, B4800, B9600, B19200 and B38400 a
    successful call to cfsetospeed() followed by a call to tcsetattr()
    shall set the output baud rate to the corresponding speed. At
    least one of these baud rates shall be supported.
    Posix Ref: Component CFSETOSPEED Assertion 7.1.2.7.2-05(C)

    Test Strategy:
    SET IXON in loop back termios structure SET IXOFF in terminal termios
    structure
    For each of the specified baud rates:
    SET input/output baud rate in terminal structure using
    cfsetispeed()/cfsetospeed()
    SET terminal information using tcsetattr()
    OBTAIN terminal information using tcgetattr()
    If input/output baud rate is not set to specified baud rate, baud rate
    is not supported

    SET input/output baud rate in loop back terminal structure using
    cfsetispeed()/cfsetospeed()
    SET terminal information using tcsetattr()
    OBTAIN terminal information using tcgetattr()
    If input/output baud rate is not set to specified baud rate, baud rate
    is not supported
    If baud rate is supported, CREATE [child process|process pair]
    Child: SLEEP using sleep() to allow terminal file to initialise
    SET time out.
    WRITE data to loop back file using write()
    VERIFY that data was written within twice the expected write time
    Parent: READ from terminal file using read()
    VERIFY that all written data can be read
    VERIFY that at least one of the specified baud rates is supported

    Test Information:
    read error. B38400 test failed
