Size of the input buffer in bytes
You configure InputBufferSize
as the total number of bytes that can be
stored in the input buffer during a read operation.
A read operation is terminated if the amount of data stored in the input buffer equals the
InputBufferSize
value. You can read text data with the
fgetl
, fget
, or
fscanf
functions. You can read binary data with the
fread
function.
You can configure InputBufferSize
only when the serial port object is
disconnected from the device. You disconnect an object with the
fclose
function. A disconnected object has a
Status
property value of closed
.
If you configure InputBufferSize
while there is data in the input buffer,
that data is flushed.
