Up until kernels >4/17, my serial stuff worked great.  As soon
as I upgraded to 5/2, the serial ports died. I get stuff like:

% cu -l /dev/tty00
Connected.
(first key I hit...)
cu: write: Input/output error

Disconnected.
%
	Now, I've already checked for conflicting IRQ's and all that;
msdos sees the serial devices just fine, and this same exact setup
worked up until 5/2, so I doubt it's the hardware.  I've also tried
every program I have that uses a serial line and get the same thing
every time.  Any Ideas?
