# This script is run by the pppd after the link is established.
#
# This script is called with the following arguments:
#    Arg  Name                          Example
#    $1   Interface name                ppp0
#    $2   The tty                       ttyS1
#    $3   The link speed                38400
#    $4   Local IP number               12.34.56.78
#    $5   Peer  IP number               12.34.56.99
#    $6   Optional ``ipparam'' value    foo

# The environment is cleared before executing this script
# so the path must be reset
