5.5.12 +FBUF? - Buffer Size
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.
Read syntax: +FBUF?
DCE response syntax: <bs>, <xoft>, <xont>, <bc>
where:
<bs> = total buffer size
<xoft> = XOFF threshold
<xont> = XON threshold
<bc> = current buffer byte count
Example:
+FBUF?
512, 506, 500, 0
