+FBUF? - Buffer Size
Read syntax: +FBUF?
DCE response syntax: <bs>, <xoft>, <xont>, <bc>
where:
<bs> = total buffer size
<xoft> = XOFF threshold
<xcont> = XON threshold
<bc> = current buffer byte count
Example:
+FBUF?
512, 506, 500, 0
The +FBUF parameter allows the DTE to determine the characteristics of the DCE's data buffer. Data buffers are used for
flow control. Use of the reported values allow the DTE to transfer data without provoking XOFF.
