All, With r264175, the uart(4) driver will no longer prevent changing the baudrate nor the CLOCAL or HUPCL control flags. What this means is that if you have a serial console on which getty(8) is started, the settings you have in /etc/ttys will now actually take effect!
To preserve the previous behaviour, change your /etc/ttys line for the serial
console to (for serial consoles on ttyu0):
ttyu0 "/usr/libexec/getty 3wire" vt100 on secure
You can replace "3wire" to "std" once you've validated that you have a carrier
signal. Otherwise setting the terminal type/class to "std" will result in the
getty(8) process getting blocked. With a carrier signal, you'll be logged out
as soon as carrier drops (i.e. when you disconnect from the console). This is
a nice feature if security is not unimportant to you.
To change the baudrate on the fly, change the terminal type/class to any of
the "3wire.XXXX" or "std.XXXX" types, where XXXX is the baudrate.
And don't forget to SIGHUP init(8) after making changes, otherwise the changes
don't take effect!
FYI,
