InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
The software package is called 'tcpser'. You can use this on any machine with a serial port to turn it into a 'modem'.
There's also a compiled version here but I haven't used it so I don't know what changes or additions that's been done.
