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.
You can get USB to parallel port converters.
I've built USB to 60ma 120VDC 45 baud serial, to drive antique Teletype machines.[1] Unfortunately, the last USB to serial chip which can go that slow, the CP2102, is approaching end of life.[2] The CP2102N, the new part, can't go that slow.
