Saving and Loading

You can save serial port objects to a MAT-file just as you would any workspace variable - using the save command. For example, suppose you create the serial port object s associated with the serial port COM1, configure several property values, and perform a write and read operation.

To save the serial port object and the data read from the device to the MAT-file myserial.mat

You can recreate s and out in the workspace using the load command.

Values for read-only properties are restored to their default values upon loading. For example, the Status property is restored to closed. Therefore, to use s, you must connect it to the device with the fopen function. To determine if a property is read-only, examine its reference pages.
