### Setting Up Ports for Use with 8-Pin RJ-45 Connectors

Using an 8-pin RJ-45 plug in Digi's 10-pin RJ-45 jack results in the loss of the modem signals RI (Ring Indicator) and DCD (Data Carrier Detect). RI is rarely necessary, but DCD is required when using modems with Unix ports.

To enable the use of 8-pin plugs, a ditty parameter, altpin, has been provided. The command

ditty altpin

swaps the functions of the DCD and DSR inputs so that DCD becomes available on pin 1 of an 8-pin RJ-45 connector.
