The RS-232C Interface
Protocol
Protocol governs the flow of data between the instrument and the external
device.
To change the protocol, select the Protocol field, then select the desired the
desired option from the pop-up selection list
With less than a 5-wire interface, selecting None does not allow the sending
or receiving device to control how fast the data is being sent. No control over
the data flow increases the possibility of missing data or transferring
incomplete data.
With a full 5-wire interface, selecting None allows a hardware handshake to
occur. With a hardware handshake, hardware signals control data flow. The
13242G cable allows the logic analyzer to support hardware handshake.
Xon/Xoff Xon/Xoff stands for Transmit On/Transmit Off. With this
mode, the receiver controls the data flow and can request that the
printer stop data flow at any time.
