Configuring HP-UX For Peripherals

Conﬁguring Terminals and Modems

Additionally Conﬁguring HP-UX for a Terminal

• The /usr/sbin/getty is the process used to set up serial terminal

and modem ports and provide the initial login prompt.

• The -h option ensures that the getty will not hang up the line before

setting the port speed.

• The -t 60 is a security option to require that the user login name and

password is typed within 60 seconds.

• tty0p3 identiﬁes the port in /dev to which the getty attaches.

• The 9600 (highlighted) does not represent the baud rate. It is a

pointer into the /etc/gettydefs ﬁle, telling the system side what

entry to use. An H entry is also provided for hard-wired terminals. See

gettydefs (4).

Step 3. Invoke the following command to activate the updated /etc/inittab

ﬁle:

/sbin/init q

Step 4. Add an (optional) entry to /etc/ttytype. Entries should conform to the

format documented on the ttytype (4) manpage. In the following example,

2392 is the terminal type; console and tty0p3 are the device ﬁle names

in the /dev directory.

2392 console

2392 tty0p3

Step 5. Now that HP-UX is set to communicate with the new terminal, verify

that the communication parameters for the terminal correspond to their

/etc/gettydefs entries. Instructions on necessary changes will be

discussed in “Differences between Console and Terminal Conﬁguration”,

the next section.

Step 6. With the conﬁguration complete, your terminal should display a login

prompt. If no login is displayed, press Return several times. If a prompt

fails to appear, consult the “Troubleshooting Terminal Problems” toward

the end of this chapter.

Conﬁguration

As shipped, HP terminals are conﬁgured properly for use as a system

console. To use the terminal as a serial terminal, the parameters shown
