Is it possible to issue a serial open command that only activates the Rx line of a com port (e.g. C2 for Com1) on a CR1000? I'd like to use the control port on the Tx line (C1) of that com port to control another sensor. I need to open the serial port for the duration of the program, but will never use the Tx line on that port. I would love to utilize that control port for other activities. Com ports and control ports are becoming precious.
I don't think it's possible but there's always the SDM-IO16 if you need more ports.
Christopher and IslandMan- did you ever get this to work out without using a sdm-io16? I have the same issue/question. I am looking at potentially using a serial open command for part of the time, to get the data off the RX line from a digital sensor, then use a serial close command, then use a control port command on the TX line of a com port to control another sensor or a communications device, then set the control port low on the TX line and go back to the serial open for the RX line etc...
do you think this would work? I will post this question separately on the forum as well- thanks!
