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. The CTS
wire is an input signal. It indicates that the other device has buffer space available,
and can receive.
In general, XON/XOFF requires a minimal three-wire connection, Ground, Transmit
Data, and Receive Data. This protocol does insert control characters into the stream
of data, and may not be appropriate for all Host systems. If supported, these control
characters are normally automatically stripped out of the data stream by Host
communication driver software, and are not visible at the application program level.
The RTS/CTS protocol requires a serial port, cabling, and Host communication
driver software that supports the additional control signals.
Command: /F[0|1][CR] Flow Control [0 = XON/XOFF, 1 = RTS/CTS]
Response: * 'iPort/AFM Ready
Default Setting: XON/XOFF
I2C General Call Control
This command enables or disables iPort/AFM response to I2C Bus General Call
(Address 00) messages.
Command: /G[0|1][CR] ' I2C General Call [0 = Disabled, 1 = Enabled]
Response: * 'iPort/AFM Ready
Default Setting: Enabled
Hex Only Display Control
This command controls Hex Only (~00...~FF) output of Master or Slave received
data.
When enabled, all received I2C message data bytes are displayed in Hex (~00…~FF)
form.
When disabled, received I2C message data bytes representing ASCII printable
characters are displayed as their ASCII printable character. Non-ASCII printable
data bytes are always displayed in Hex (~00…~FF) form.
