Synopsis: When MIN>1 TIME>0, poll() on tty succeeds but read EAGAINs

State-Changed-From-To: open->closed
State-Changed-By: dsl%NetBSD.org@localhost
State-Changed-When: Sun, 20 Dec 2009 11:23:23 +0000
State-Changed-Why:
VTIME > 0 seems to override O_NONBLOCK (probably once 1 char is read) so
the program no longer loops.
With VTIME == 0, VMIN == 2 poll doesn't return until 2 chars are available.
So sometime it has all been fixed.
