I have a WATLOW 942 controller that I routinely communicate with via a serial port on my laptop's serial interface on the docking station. We received a new laptop where the docking station does not have a serial port. We do have a USB to serial interface cable, but I have not figured out yet how to use ASRL using the examples in these threads. I can get connection expert to see the serial controller, but I can't seem to send a simple command. Any thoughts?
Enclosed is the serial setup that works fine. Only caveat is \r is the terminator and EOL.
