1. Install the modem on the server communication port and ensure that the operating system recognizes the port.

2. From the IBM® Lotus® Domino™ Administrator, select the Server - Status tab.

3. From the Servers pane, select the server on which to set up the port. On platforms, such as UNIX®, for which there is no Domino Administrator client, you can set up ports remotely.

4. From the Tools pane, click Server - Setup Ports.

5. Select the name of the port on which you installed the modem, for example, COM1.

If the communication port name does not exist, select New, type the name of the communication port on which you installed the modem, select XPC for the driver, and then click OK.

7. If you want to enable Domino network data encryption, select "Encrypt network data."

Note Enabling network encryption can slow performance, especially for connections that use data-compressing modems. Never apply Domino network data encryption to ports that use data-compressing modems. Rather than reducing the size of the transmitted data, the modem's hardware compression techniques can increase it, negating the benefits of the modem compression. For more information about setting up network data encryption for a port, see the topic Encrypting network data on a server port.

9. Click portname Options, where portname is the name of the port whose settings you want to change.

10. Modify default port settings, as needed and then click OK.

Note These settings apply to digital-analog modems only, not cable or DSL modems.

The default port settings work in most situations. However, if you are performing troubleshooting, you may wish to adjust some of the settings. The following settings are available:

Field	Description
Modem type	Associates a modem with a modem command file. If none of the listed modems is an exact match for the installed modem, select the closest match by brand and speed. If the modem is 100% Hayes-compatible, select "Auto Configure" (AUTO.MDM) for Domino to determine the modem type automatically and select the appropriate Hayes command file. Because the Auto Configure modem file does not provide optimal performance, use it only as a temporary measure while obtaining an appropriate modem If there's no match and your modem is not 100% Hayes-compatible, you may need to edit an existing modem command file or create a new one. For information about your modem, see your modem documentation. For information about editing modem command files, see the topic Modifying a modem command file.
Maximum port speed	Specifies the maximum speed at which the communication port on the computer sends data to the modem and receives data from the modem. Domino selects a maximum data transmission speed based on the modem type you select. The maximum speed is limited by the maximum speed specified in the modem's command file and may also be limited by the server's operating system. Default value is 19200. Specify the highest value supported by your modem hardware. Select a lower port speed if you are having trouble with a noisy phone line or cannot establish the carrier. Note When using a null modem, the maximum port speed on both computers must match.
Speaker volume	Specifies how loudly to amplify modem tones during connection attempts. Choose the volume that best allows you to monitor call progress: Low Medium, or High; or choose Off to mute the modem.
Dial mode	Choose one: Tone - For touch-tone phone lines. Pulse - For rotary phone lines or modems that do not support touch-tone dialing.
Log modem I/O	Select this option to help troubleshoot modem connection problems by recording modem control strings and responses in the Miscellaneous Events view of the server's Notes Log (LOG.NSF). To conserve disk space, after the problem is fixed, deselect this option to prevent the extra information from being recorded.
Log script I/O	Select this option to help troubleshoot communication problems between servers that occur after the modem establishes a connection. The server records script file responses and replies in the Miscellaneous Events view of the server's Notes Log (LOG.NSF). To conserve disk space, after the problem is fixed, deselect this option to prevent the extra information from being recorded.
Hardware flow control	Specifies how data is sent between the computer and the modem. Select this option (the default on operating systems other than UNIX®) to enable data flow control. Deselect this option only if you're using a modem or external serial port that doesn't support flow control. When deselected, messages about errors and retransmissions can appear in the Phone Calls view of the log file (LOG.NSF).
Wait for dialtone before dialing	Select this option (the default) to require the modem to detect a dialtone before dialing. Deselect this option on phone systems where dial tone detection is a problem.
Dial timeout	Specifies the time, in seconds, that the source server continues attempting to connect to the destination server before it cancels the attempt. Increase the dial time-out period when using pulse dialing or when calling overseas. The default value is 60.
Hangup if idle	Specifies the time, in minutes, that the modem on the source server waits before hanging up if there is no data passing through the connection. The default value is 15. For ports that workstation users dial into, specify a longer idle time so users have time to read or compose long documents.
Port number	Specifies the port number for the current port type. Domino automatically sets the port number to the number specified in the port name -- for example, if COM7 is the port name, the port number is 7. On UNIX® systems, specify a port number N that matches the /dev/cuaN device file that you linked to the asynchronous port.

12. If necessary, you can edit acquire scripts and modem command files.
