Configuration overview
The following is a summary of the configuration procedure:
1 Configure a DTC port to be a printer port
• See chapter 10, "Changing Port Type to Terminal, Printer or Host" to
change the port type to printer.
• See chapter 11, "Configuring Terminal, Printer and Host Ports" to set the
other port parameters.
2 Associate a device file with the printer using the DDFA device file utilities, see
“Creating the Device File Name with the DDFA Utility” on page 109.
3 Configure a printer on the DTC for the HP-UX spooler, see “Configuring a DTC
printer for the HP-UX spooler” on page 111.
4 Test printing to a printer, see “Testing the printer configuration” on page 112.
DTC Device File Access utilities
DTC Device File Access utilities (DDFA) provides an interface to remote DTC
ports which is similar to the interface for local MUX ports and comprises a group of
configuration files, executable files, and a daemon. The DDFA software is part of
Internet Services and is automatically installed with it on HP 9000 Series 300, 400,
700, and 800 systems for HP-UX 9.0.
DDFA is intended for DTC users who need to access DTC devices by using pty
device files names. Without DDFA, pty device file names are assigned randomly to
devices on DTCs. This randomness makes it difficult to associate a specific pty
device file with a specific device connected to a DTC.
DDFA allows the system or network administrator to configure a correspondence
between the DTC IP address and port with specified pty device file names. Devices
on the DTC can then be referred to by their pty device file names. For example,
these pty device file names can be used with standard read(), write(), open(),
close(), and ioctl() calls.
DDFA can also be used to identify a DTC printer with the HP-UX spooler. The
HP-UX spooler requires devices to be identified by their device file names. For each
device that is directly connected to the system, a device file name is assigned by the
system administrator.
