Hi, I'm Jose, i'm new in here.
Some time ago I wrote a module to control an RS232 cooler and now I am writing a new module for MR-J3 servo drives via RS422, but I couldn't open this second port, does anyone know if it is possible to use more than one serial port at that time in mach4, would it be a problem in my code? My programming knowledge is basic. I will open and close the ports for each communication, but the chiller script updates the temperature continuously, so I would prefer to leave it open all the time.
Thanks for any help Jose
