Modem Sharing Sharing Modems
10-2
Ports associated with a service used for modem sharing must support outgoing connections. To support
outgoing connections, the port access must be set to Dynamic or Remote.
Figure 10-4: Configuring a Port for Outgoing Connections
A port associated with a service used for modem sharing must also be configured to operate the modem
attached to it. To configure modem operation on a port, use the following commands:
Figure 10-5: Configuring Modem Operation on a Port
To display a particular modem type’s settings, use the Define Ports Modem Type command, discussed in
detail on page 12-105.
Note: For more information on modem configuration, see Chapter 9, Modems. For
more information on port configuration, see Chapter 8, Ports.
10.1.3 Displaying Current Services
To display a list of the current services, use the Show/Monitor/List Services command.
To display specific information about a service, the following parameters may be used with the Show/
Monitor/List Services command: Characteristics, Summary, and Status. For example, to display a
service’s characteristics (including the ports associated with it), use the following command:
Figure 10-6: Displaying a Service’s Characteristics
The command above shows the ports associated with the service fastmodems, the characteristics enabled
for the service, and the service rating.
Generally, a service rating of 255 means that the service is available, and a rating of zero means that it is
busy or otherwise unavailable. A rating between 255 and zero indicates that the service is partially available.
For example, fastmodems may be a modem pool containing three high-speed modems, one of which is
available. In this case, the service rating for fastmodems would be 85.
Note: Show/Monitor/List Services is discussed in detail on page 12-114.
