That’s disappointing. That was a useful hack. I know everyone thinks that Serial stuff is going away, but vendors keep selling me instruments that use it.
For example, we bought a reactor system that came with Exlar slide valves with linear actuators. They came with software you could hook up to a COM Port on your computer. We wired them through a SNAP-485-422 module and were able to communicate with them via our Opto chart AND their software (not at the same time) without changing the wiring. Handy!
Not sure if it would be possible to add this functionality to the CSERI – a port to get to the serial device. Python code for this is out of my league.
