I got the idea from digging through cornell gated... i grabbed something off the net called bsd-mslip.tar.gz, a multi-line slip thingie. i have not used it myself, havent needed it yet. the 'ads' file is at the bottom.

Main features and differences from standart SLIP driver: 1) Multiline SLIP protocol are realised. It allow you to use few lines for the same SLIP connection, all this lines would work in parallel. 2) Keepalive protocol are realised. It checks if any packets are received from this line, and drop connection (and reestablish it) if no this packets was received during defined time. In addition, driver can be configured to wait few packets from the line before interface would be turned on. Driver can send dummy _keep alive_ packets every N seconds to keep line _alive_ even if no routing / icmp packets are transmitted between systems. 3) Driver fixes interface numbers for every line, to prevent routing problems (most routers dislike if some interface change it's addresses fast). 4) Driver can turn off BPF protocol on per-port basis. 5) Somwe bugs fixed. 6) interface accounting was added. There is utilities to work via leased, dial-in and dial-out lines. This programs allow to receive dialin connections, install dialout or leased lines connections (both with and withouth modem's control), allow to install leased line connections with dialout back-up, and so on. ================================================================= This driver is used in PC-Based routers - we work with 24 slip lines via digiboard plates, under heavy load.
