Log:
Explicitly list the i/o addresses of the serial ports.
Prompted by docs/12343, in which people seemed to get a little confused.
The original text in the file said:
[...]
# By default we use COM1 as our serial console port *if* we're going to use
# a serial port as our console at all. (0x3E8 = COM2)
#
#BOOT_COMCONSOLE_PORT= 0x3F8
[...]
From what I can make out, some people have assumed that means that if
they just uncomment the BOOT_COMCONSOLE_PORT then it will use COM2:
These same people then assume that "0x3F8" on that line is a typo for
"0x3E8".
What it actually means is that if you uncomment the line then the default
stays as "Ox3F8" (COM1:), and that you have to uncomment the line, *and*
change the value of the variable in order to use COM2:.
So I've made that a little bit clearer. I've also listed the hex values
for COM1: thru COM4:, snarfed from sys/isa/isareg.h.
