    Test Description:
    If general terminal interface supported:
    When ICANON is clear, MIN > 0, TIME > 0, and data is in the buffer
    at the time of the call to read(), then the timer is started as if
    data had been received immediately after the call to read().
    Posix Ref: Component Terminal Interface Assertion 7.1.1.7.1-35(C)

    Test Strategy:
    OPEN and initialise terminal file and loop back file
    CLEAR ICANON and ECHO in terminal control flags
    SET VMIN to READ_MIN and VTIME to 2*READ_TIME
    WRITE READ_MIN-1 characters to loop back file file using write()
    SLEEP for longer than the inter-byte timer
    WRITE 1 character to loop back file file using write()
    SLEEP for 2 seconds
    SET time out for READ_TIME/10 (half of inter-byte timer)
    READ from terminal file using read()
    VERIFY that read() returned size of data written
    VERIFY that read() was not interrupted by alarm, so read() returned
    before timer expired

    Test Information:
    read() returned 9, expected 10
