A) what does this message mean? and what are users expected to do with
their /etc/rc.serial?
"Use of setserial/setrocket to set SPD_* flags is deprecated"
It means that you're not supposed to use setserial to set "spd_hi",
"spd_vhi", etc. to set 57600, 115200 baud rates. You should simply have
your applications set the desired buad rate directly, instead of using
the kludge of spd_hi/spd_vhi/etc. setting the baud rate to be 38400.
This is a horrible kludge that hasn't been necessary since the 1.2
kernel, so applications really have no excuse to still be using this
mechanism.
