Planning to Configure a Terminal or Modem

Plan ahead before configuring a terminal or modem. Read the hardware documentation shipped with the peripheral device and understand what you need to do before getting started.

Planning to Configure a Port for a Terminal

Consider the following:

Are you configuring the device directly to a serial (RS-232-C) port or to a terminal server through the LAN?
Will other users be affected by the configuration? If so, notify them before you bring the system down.
Observe HP recommendations concerning maximum recommended cabling distances and maximum number of terminals per interface.
Decide whether you will be running uucp on the device.
Invoke /usr/sbin/ioscan -f before beginning your configuration to figure out to which interface card or MUX you are adding the terminal or modem. Note which ports are already used. Attempt to distribute the peripherals among your cards, if possible.

HP systems are shipped so that you can use the HP console terminal immediately after plugging it into an SPU.

The simplest way to configure any HP terminal or a modem is to use the System Administration Manager (/usr/sbin/sam). SAM's self-explanatory menus and help system prompt you for all the software requirements, to ensure the terminal or modem is configured properly and with appropriate security settings. If SAM is not loaded on your system or if you prefer to use the command-line interface, the following procedure will guide you through the task. Familiarize yourself with the instructions before getting started.

Planning to Configure a non-HP Terminal




	NOTE: As of 10.0, HP provides limited support for non-HP terminals. Their configuration and limitations are discussed in the section, “Configuring a Non-HP Terminal as a Console”, later in this chapter.

The following non-standard terminal emulations are provided for HP-UX:

DEC VT100, VT320
VT420 terminals in VT100 or VT320 modes
Wyse 60
HP terminal 700/60 in VT100, VT320, and Wyse 60 modes.

Note, the less expensive DEC and Wyse terminals lack certain capabilities standard to full-featured HP terminal firmware. See “Limitations to Non-HP Terminal Emulation” for information on the differences.

Planning to Configure a Port for a Modem

To add a modem to an HP system, you need to configure both the serial port for HP-UX to recognize the modem and the modem's protocol. Regardless of whether you configure using SAM (recommended) or HP-UX command-line interface, read the procedure and modem documentation beforehand.

Consider the following choices:

The hardware path (including port number) of the serial interface to be used by the modem. You can identify potential ports by invoking /usr/sbin/ioscan -C tty or list /dev/ttyxp*, where x is the mux card instance and p* shows all existing ports.
The modem's baud rate.
Whether the modem will be used for outgoing calls.
Whether the modem will receive incoming calls.
Whether the modem requires CCITT (required only by certain European government protocols). For standard Hayes-compatible modems that use CCITT modulation and compression standards, do not use CCITT mode. See modem(7) for details of RS-232-C signaling characteristic of simple and CCITT modems.
Whether you need to configure for UUCP connectivity.

You will need to create device special files with /usr/sbin/mksf specifically for modem use.

mksf provides options for CCITT for special European protocol requirements (most US customers should not use the CCITT option), -i option for a UUCP dialer (used with access mode 0), and hardware flow control (an alternative to XON/XOFF pacing). The mksf options for the asio0 device driver allows for incoming and outgoing hardware buffering.

An example of creating modem device special files is provided in “Additionally Configuring HP-UX for a Modem”, later in this chapter.

See the mksf(1M), modem(7), and termio(7) manpages in the HP-UX Reference for bit values and use. Also review “Requirements for Modems to Work on HP-UX” to ensure proper functioning.
