#!/bin/sh
#
# /etc/init.d/serial 
#
# Initializes the serial ports on your system
#
# Without uncommenting some of the lines in this script, you'll be unable to
# use ports other than the first two, and those only if they use "standard"
# IRQ values (whatever those are... :^)  The rc.serial script made a couple
# machines I tested this on hang at this point in the boot process, so it's
# commented out by default. However, if you need to set up extended serial
# ports, it's a very good starting point. It usually works great.
# More info that will be useful: I did some testing and found that the lines
# in /etc/rc.d/rc.serial that are most likely to make the machine hang are the
# one that sets up /dev/ttyS3, and the last time, which causes a report to be
# issued to the console about how the ports were configured. This tries to
# report on *every* port... if you change it so it only lists the ports you're
# going to use (/dev/ttyS0 /dev/cua1 /dev/cua2 for example) that it probably
# won't cause a hang. Also, the "wild" interrupt detection used for auto-
# configuration can cause problems as well. I highly recommend using the
# manual configuration lines to avoid trouble.
