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?
