Handshake (About Buffer Flow Control) ___________________________
Control during
Receiving
When using hardware (RTS/CTS control):
When the data in the receive buffer exceeds 85% of the buffer, CA(RTS) is set to
OFF and the controller is notified that there is not much space remaining in the
buffer.
Processing of the data in the buffer continues, and then CA(RTS) is set to ON
and the controller is notified that there is sufficient remaining space in the buffer
when the amount of data becomes less than 25%.
When using software (XON/XOFF control):
When the data in the receive buffer exceeds 75% of the buffer, XOFF(13H) is
sent and the controller is notified 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 notified that there is sufficient remaining space in the buffer when
the amount of data becomes less than 25%.

If a PC is used to read data from the Models 3504-40, 3504-50, 3504-60 unit
immediately after the power of the Models 3504-40, 3504-50, 3504-60 unit is
turned on, undefined values may be read because of BA(TxD) being unstable.
After turning the power on, wait at least six seconds before starting to read
data.
