6.1.2 Auxiliary Channel: Handshaking Disabled.

The SSP-200/300 ports may be configured so that the RTS-CTS handshake is disabled. This is the default configuration. In this configuration, RTS and CTS from the 16C750 UART will be looped back to each other. In addition, the auxiliary output and input signals will be looped back to each other. This configuration is shown below:
