Buffer Space
Send XON
Send XOFF
XON/XOFF control:
• When the data in the receive buffer exceeds 75% of the
buffer
,
XOFF(13H) is sent and the controller is notied
that there is not much space remaining in the buffer.
• Processing of the data in the buffer continues
,
and then
XON(11H) is sent and the controller is notied that there
is sufcient remaining space in the buffer when the
amount of data becomes less than 25%.
Control during Sending
XON/XOFF control:
• When XOFF is received
,
the sending of data is halted. When XON is received
,
the sending of data is
resumed.
