Fixed the uart(3) manpage and removed the 't' option from the control messages, as it
does nothing in the current kernel.

    These fixes aren't correct.

    	  Reads of the data file will block until at least one byte is available.
    	  The
    
    These were right before.  The file name is "eian", not "eia n",
    so you should use BI.  It looks like you also alphabetized the
    control messages.  That's great.  Please submit that part again.

    If you remove this, then you should also remove dcdts from uart.h.
    
    Thanks.
