When Linux was just getting its network stack happening, I wrote scripts that managed the modem, and being as reliable as modems were, ensured that if the link was lost, it would redial and re-establish the network. Basically it was "aware" if the network was down but shouldn't be. There also weren't so many licenses around yet, so I just made it public domain with only a request that people who used it emailed me so I knew it was still useful and worth updating, etc. My scripts were in the LSM (Linux Software Map), which was about as official as things got back then. They fell out of use once networking became more stable, and daemons were ... daemonizing properly.
