Use this procedure to configure devices to use alternate wiring if you will be using 8-pin RJ-45 plugs with Digi's 10-pin RJ-45 jacks. This procedure uses a ditty parameter, altpin, to enable the use of 8-pin RJ-45 connectors. This is accomplished by swapping the functions of the DCD and DSR inputs so that DCD becomes available on pin 1 of an 8-pin RJ-45 connector.
ditty altpin [device_name]
(in AIX, use /usr/Lbin/tty/stty-digi altpin
[device_name])
where device_name is the name of the TTY
device on which you want altpin activated. If no device is
specified, the command acts on stdout.
To cancel altpin, enter the following command:
ditty -altpin [device_name]
(in AIX, use /usr/Lbin/tty/stty-digi -altpin
[device_name])
