Buffer Size
Enter the maximum size (in bytes) of the data array that you are planning on
sending and receiving. Valid values are from 1 to 65536; the default size is 82.
When the controller sends out the data, if it detects an array that is larger than
this buffer size, a minor fault occurs and the extra data is truncated. When the
controller receives data, if it detects data that is larger than the size of the
buffer, the extra characters are dropped.
