How to get the data from the RS 232?

I have a RS232 that connected to the Computer at COM 1.

Then, I want to recieve the data from the RS 232 in real-time.

Using the below simulink blocks, is it possible to recieve the data?

Hi Changwoo Lee,

Based on your description, you have an RS232 connection established between your computer and Com1, and you wish to receive real-time data. You are uncertain about using the Host Serial Receive block for this purpose.

Receiving data in real time through serial connections, specifically RS232, is indeed possible. The documentation mentioned below provides information about the feasibility of using the Host Serial Receive block for this task.

To establish communication and configure the receiver block, please refer to the provided answer as an example. You can use it as a starting point and adapt it to suit your specific use case and requirements. The answer’s zip file contains a pdf file talking in detail about different configurations for simple read block.
