(Not recommended) Stop asynchronous read and write operations
This serial object function is not recommended. Use serialport
object functions instead. See Compatibility Considerations.
stopasync(obj)
stopasync(obj) stops any asynchronous read
or write operation that is in progress for the serial port object,
obj.
You can write data asynchronously using the fprintf or
fwrite function. You can read data asynchronously using the
readasync function, or by configuring the
ReadAsyncMode property to continuous.
In-progress asynchronous operations are indicated by the
TransferStatus property.
If obj is an array of serial port objects and one of the objects
cannot be stopped, the remaining objects in the array are stopped and a warning is
returned. After an object stops:
Its TransferStatus property is configured to
idle.
Its ReadAsyncMode property is configured to
manual.
The data in its output buffer is flushed.
Data in the input buffer is not flushed. You can return this data to the MATLAB® workspace using any of the synchronous read functions. If you execute the
readasync function, or configure the
ReadAsyncMode property to continuous, then
the new data is appended to the existing data in the input buffer.
