# possible commands:
#
# sleep
#
# goto <failure-target>
#
# dcdwait <timeout> <failure-target>
#
# dsrwait <timeout> <failure-target>
#
# ringwait <timeout> <failure-target>
#
# send <timeout> <failure-target> <string>
#
# wait <timeout> <failure-target> <string>
#
# expect <timeout> <failure-target> <string>
#
# :<failure-target>
#
# 'timeout' is the time within the command must complete in seconds,
# a minimum of one second must be specified
#
# 'failure-target' is a jump target at which execution continues if
# a timeout occurs, 'done' is a special target that terminates
# execution successfully, 'fail' is a special target which
# terminates execution with error
#
# 'string' is a string sent or received which must not contain
# any blanks or tabs but which may contain the following
# escape sequences:
#	\\	backslash
#	\b	blank
#	\t	tab
#	\r	carriage return (the enter key)
#	\n	line feed (^j)
#
# 'sleep' delays execution for a second
#
# 'goto' jumps unconditionally to the given target
#
# 'dcdwait' waits for the data carrier detect line of the modem
# to be active
# 
# 'dsrwait' waits for the data set ready line of the modem
# to be active
# 
# 'ringwait' waits for the ring indicator line of the modem
# to be active
# 
# 'send' sends the given string to the modem device
#
# 'wait' reads lines from the modem device until
# a line is read that contains the given string
#
# 'expect' reads one line from the modem device which
# must contain the given string
#
# ':' is the failure jump target
#
# you may test a modem init script with the 'vpnd -t [-f <config-file>]'
