COM port does not work

In my evaluation process I want to test the comport. I try to use ComRcvStr.
I get it to log COM1: open COM1:Close on opening and closing but it does not register incoming data.
Is this a limitation in the Free version or ?

The only limitation of FlowStone FREE is that you can only have one COM port device at any time.

You say you are using ComRcvStr (Com Port Receive Strings) is it strings that you are receiving or byte data?

There is also a ComRcv for Byte data which is a different module.

I would suggest the you try sending data first as it is easier to setup. Obviously make sure you have the correct: Baud, Stop bits, Data Width, Parity etc.

There is a COM Port example in the Example Schematics you can download called: LynxMotion SSC-32 Servo Controller

FYI: we have just made a new COM Port module that does everything in one module (Strings and Hex Data In & Out).

This should solve any issues you had and make it easier to use. Also it means that you will be able to get data in and out in FlowStone FREE as it is a single module :)

This will be in the new update next week!

I have similar problem but with the new release comport module.
I am using flowstone from my notebook to communicate with a calibrator through com port 1
Using Moxa Uport 1110 USB to RS232 converter to the calibrator's com port
I am able
1. open and close the com port
2. log the activity on com port

but unable to get any feedback
It works fine when using hyperterminal with the same setting and command.
9600 baud
8 data bits
1 stop bit
no parity
Command : "*IDN?"

I try changing to com: 2,3,...20 but can only work with com:1.
Please advice
