+Summary: serial port blcoking read with timeout seems broken
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+With the PosixHelper lib (libmono0_1.1.17-2) installed and using:
+read_serial(unixFd, buffer, offset, count, readTimeout)
+to make blocking serial port read calls does not properly honor the
+requested timeout (anymore).
+Also, the behavior of the Parity enumeration has changed, but this appears
+to be intentional (to match .NET2.0)??
+Steps to reproduce the problem:
+Do a blocking read with a non-zero timeout when no data has actually been
+Actual Results:
+It blocks forever.
+Expected Results:
+It should return with a timeout indication (received character count = 0)
+How often does this happen? 
+Every time.
+Additional Information:
+A different recent version (libmono0_1.1.17-1) seemed to have a related
+bug, where the read would not block at all (with a non-zero timeout parameter).
