Use this information to configure devices to use alternating wiring if you will be using 8-pin RJ-45 plugs with Digi's 10-pin RJ-45 jacks.
Use the ditty parameter, altpin, to enable the use of 8-pin RJ-45 connectors. The command
ditty altpin /dev/ttyh2d
swaps the functions of the DCD and DSR inputs so that DCD becomes available on pin 1 of an 8-pin RJ-45 connector. The device /dev/ttyh2d is just an example. Specify your device instead.
