Close I2C Connection

This command disconnects iPort/AFM from the I2C Bus.

Command: /C[CR]	'Close I2C Connection
Response: /CCC[CR]	'Close Connection Complete
Default Setting:	'Closed

Set Destination I2C Slave Address

This command sets the destination I2C Slave Address (Hex 0,2...FE) for all subsequent Master Transmit or Receive operation.

Command: /Dxx[CR]	'Set Destination I2C Slave Address
Response 1: *	'iPort/AFM Ready
Response 2: /I89[CR]	'Invalid Command Argument
Default Setting: 00

Echo/Prompt Control

This command enables or disables data entry echo and prompts used as feedback to manual operations from a computer terminal.

Command: /E[01][CR]	'Echo/Prompt Control [0 = Off, 1 = On]
Response: *	'iPort/AFM Ready
Default Setting:	Off

Flow Control

This command selects the serial communication handshaking protocol to be use in communicating with the Host computer.

iPort/AFM implements either XON/XOFF (by default) or RTS/CTS flow control protocols. Flow control is used by the iPort/AFM 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 11) is used to enable the flow of data. XOFF (Hexadecimal 13) is used to stop the flow of data.
