# Start/stop ELKS networking
#
# Usage: net [start|stop|restart|show] [ne0|wd0|3c0|slip|cslip] [baud] [device]
#
# Examples:
#	net start ne0			start ethernet networking
#	net start slip			start slip networking
#	net start slip 19200	start slip at 19200 baud
#	net start cslip 4800 /dev/ttyS1
#	net show				shows settings for 'net start'
#
# See slattach.sh for Linux slip setup
# See qemu.sh NET= line for host forwarding into ELKS using QEMU
#
#set -x

# read net configuration file
