Serial Communications Flow Control
Select the serial communication handshaking protocol to be used in communicating
with the Host computer.
iPort/LAN implements either XON/XOFF (by default) or RTS/CTS flow control
protocols. Flow control is used by the iPort/LAN to limit character flow to and from
the Host computer to avoid overflowing internal communication buffers and lost
data.
The XON/XOFF protocol inserts characters directly into the ASCII data stream.
XON (Hexadecimal 0x11) is used to enable the flow of data. XOFF (Hexadecimal
0x13) is used to stop the flow of data.
The RTS/CTS protocol uses two additional wires in the cable connecting
communicating devices. The RTS wire is an output signal. It indicates that the
device generating the signal has buffer space available, and can receive data. The
CTS wire is an input signal. It indicates that the other device has buffer space
available, and can receive more data.
