# Name: fctStartAdsl
# Goal: start ADSL connexion (do not display anything)
# Author: Tux
# Version: 1.9.5
# Params:
#	h = display help
#	m = start mire
#	s = simple mode (don't use ifup & ifdown scripts => do not requiere ifcfg-ethX)
#	t = set timeout delay (default=60s)
#	a = use ip address (use -a xx.xx.xx.xx), imply simple mode
#	d = launch pppd in debug mode
#	i = only put modem interface up (ifup ethX)
# Error codes:
#	1 = pppd already lauched (non degroupé)
#	2 = modem can't be synchronized
#	3 = can't launch pppd
#	4 = can't set modem interface "up"
#	5 = lock still present
