There is no master-slave relationship in ppp...the ends are peers. Upon starting the interface it should send "n" configs, and then stop if no reply is received. When a config is received it starts again. The state machine allows for this nicely. One problem is when the electrical interface (UP) is not implemented (ie, receipt of DSR) properly. You should not be able to get into both ends being dormant if its done properly. Dennis
