Configuring a TTY Device for a Modem Using RealPort Configuring a TTY Device for a Modem Using RealPort Use this procedure to configure a RealPort device for a
Dial-in/Dial-out modem connection. Configuring a device for a modem
requires familiarity with both the operating system and the modem
being used. While the following procedure is sufficient for most
cases, it may be necessary to take additional steps to properly
configure your modem or to set up the operating system for a
specific application.
The Digi device and RealPort should be properly installed,
configured and functioning before proceeding. This procedure
assumes that a tty has been created for the modem. See Creating and Configuringttys.
Procedure
- Turn the modem on.
- Access a root prompt on the AIX system.
- Add an entry for the device in the file /usr/lib/uucp/Devices.
The following example allows a connection of 9600 baud to the
device:
Direct tty3 - 9600 direct
- Use the following command to connect to the modem:
cu -ml ttyX
In this command, ttyX is the device name for the port.
The modem should respond with an AT prompt.
- Train the modem to the port speed by entering this command at
the AT prompt:
at&w
- Terminate the connection by entering:
~. (a tilde followed by a period)
and choosing Enter at the AT prompt.
- At an AIX root prompt, enter this command:
smit tty
- Choose Change/Show Characteristics of a TTY.
- Choose a TTY device. This is an example of a listed device:
tty7 Available 00-00-04-02 Asynchronous
Terminal
In this example, the first 00 is the bus number. This is unused
and will always be 00. The second 00 is the slot number. This is
unused and will always be 00. The number 04 is the sa device
number. The number 02 is the port number.
- Set Enable LOGIN to share.
- Set BAUD rate to the modem's highest configurable baud
rate.
- Set PARITY, BITS per character, and number of STOP BITS to
match the settings of the modem.
- Set FLOW CONTROL to be used to match the flow control used by
the modem.
