Number of bytes available in input buffer
BytesAvailable indicates the number of
bytes currently available to be read from the input buffer. The property
value is continuously updated as the input buffer is filled, and is
0 after the
You can make use of
BytesAvailable only when reading data asynchronously.
This is because when reading data synchronously, control is returned to the
MATLAB® Command Window only after the input buffer is empty. Therefore, the
BytesAvailable value is always 0.
BytesAvailable value can range from zero
to the size of the input buffer. Use the
to specify the size of the input buffer. Use the
to return the total number of values read.
