This is not a regression from 1.5.18, which I know worked fine with serial
I/O.  I will try to test 1.5.23 when I get a chance, but I have no reason
to suspect it is broken.

CREAD appears to always be enabled but not indicated by tcgetattr or
controllable via tcsetattr right now.  So, the test case above is not
indicative of the original problem.

To the OP, posting your code might be informative.
