Algorithm (Workflow)

This function, serialportused, is designed to identify serial ports that are currently in use on a system. It is part of the SolidGeometry library, specifically introduced in version 5.1, and is categorized under auxiliary procedures.

Input Parameters

The function serialportused does not take any input parameters. It operates without requiring any arguments from the user.

Output

The function returns a variable su, which is a list of serial ports that are currently in use.

Algorithm Explanation

The function utilizes two key MATLAB functions: serialportlist("all") and serialportlist("available").

• serialportlist("all"): This command retrieves a list of all serial ports available on the system, regardless of their current status (in use or available).
• serialportlist("available"): This command retrieves a list of serial ports that are currently available for use, meaning they are not occupied by any process.

The core operation of the function is performed by the setdiff function:

su = setdiff(serialportlist("all"), serialportlist("available"));

The setdiff function calculates the difference between the two lists: all serial ports and available serial ports. The result is a list of serial ports that are in use, as these are the ports present in the "all" list but absent from the "available" list.

Example Usage

To use the function, simply call it without any arguments:

serialportused

This will return the list of serial ports that are currently in use.

Related Functions

The function is related to other functions such as raamboterminal and serialportlist, which may be used for further serial port management and operations.

Overall, the serialportused function provides a straightforward method to identify which serial ports are occupied, aiding in debugging and resource management tasks.
