When we dial using the post dial up window & connect, it's an exec session untill we hit the cntrl 7 or done button..... the NAS (into which we dialin) when configured for dedicated PPP connection, we start seeing garbage on the screen since the NAS is sending LCP packets out towards the dailin client.
By hitting cntrl 7 or done we are basically transfering the exec session to the PPP stack on the PC operating system...from there on the NAS & the client PC negotiate PPP.
On the NAS if we configure "autocommand ppp" under the lines then we will negotiate ppp.
Thanks, Mak.
