Creating the Device File Name with the DDFA Utility

the printer is connected.

b Choose the device file name for this printer. You can choose any name, but

you might want to include some port information, for example you could

choose /dev/dtc1p2 to indicate that the device file name is associated with

port 2 of dtc1.

c Edit the /etc/ddfa/dp file, using vi for example, and create an entry for

each printer in the file of the following form:

The slash (/) must separate the board and port parameters.

For example, a printer is on port 2 of a DTC with an IP address of

192.101.23.45. You want to refer to this printer as /dev/dtc1p2. The

entry in the dp ﬁle would be:

Note For a DTC, the board number should be 1 or 01. Valid port values are 0 to 15.

Each printer must have a pcf ﬁle associated with it. Several devices can

have the same pcf ﬁle, or they can each have a unique pcf ﬁle. Usually, the

default pcf ﬁle is sufﬁcient for most applications or systems.

7 The file ddfa/dp is protected. In vi, to save your changes, use the command wq!.

8 Implement your changes by entering the following command.

dpp ddfa/dp -k

This executes the dedicated port parser (dpp) to scan the dp ﬁle and start up an

ocd (outgoing connection daemon) process for each entry in the dp ﬁle.

9 Verify that the ocd process has been started by looking at the output of the

following command:

ps -ef |grep ocd

10 To ensure that the ocd processes are started correctly each time the system is

started up, add the following entry to the file /etc/rc:

192.101.23.45 1/2 /dev/dtclp2 /etc/ddfa/pcf
