Nothing in this area has changed for several months.

Processes hang closing ttys if there is output to drain and crtscts is
set and CTS has gone away.  They can be unwedged after 1 second using
`comcontrol /dev/ttydN drainwait 1'.  1 second is too small for general
use.  /etc/rc.serial suggest using 180 seconds.  `stty -crtscts </dev/ttydN'
should work but is currently broken.
