I upgraded an old 1.1.5.1 system to -stable a few days ago and had
trouble convincing cu to talk to a port that only has TX and RX.
I had to stop cu and turn off crtscts to get cu to output.  Input
works OK.  Once I understood the problem, I tried the locking/initial
mechanism but -crtscts would not stick.

-current from last month cu defaults to:

cflags: cread cs8 -parenb -parodd hupcl clocal -cstopb -crtscts -dsrflow
        -dtrflow -mdmbuf

-stable from last week:

cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb crtscts -dsrflow
        -dtrflow -mdmbuf

Has cu changed or have the kernel defaults changed?  Is the
locking/initial scheme broken in -stable?
