No, no BBS here. It's part of an old data-collection system we have at work. We have water quality measurement devices attached to a TNC+radio on battery+solar panels that are several miles away from our main offices. Periodically we poll those devices to see what the current conditions are.

I think only 2 of the stations still use packet radio. The rest have been moved to spread spectrum radio. But the existing packet radio system has been in place since 1990 and the original data collection software was written in good ole perl4 :-)
