Prior to FreeBSD version 2.2.5, once the link was established, ppp(8) would wait for the peer to initiate the Line Control Protocol (LCP). Many ISPs will not initiate negotiations and expect the client to do so. To force ppp(8) to initiate the LCP, use the following line:
set openmode active
Note: It usually does no harm if both sides initiate negotiation, so openmode is now active by default. However, the next section explains when it does do some harm.
