8.8.7 Dialback
The Dialback feature allows a system manager to set up a dialback list of authorized users for incoming
modem connections. When a username matching one in the list is entered, the port is logged out and the
phone number will be sent out the serial port using the port’s modem profile.
For a complete description of dialback, see Dialback on page 11-6.
8.8.8 Enabling Menu Mode
If you want to limit user access to the Local> prompt, you can set up a menu with restricted options. The
Set/Define Ports Menu enables menu mode for the specified ports.
Figure 8-29: Enabling Menu Mode
When Menu mode is enabled, the Local> prompt cannot be accessed. Be sure that you have another way to
log into the SCS before enabling Menu mode on all ports.
Note: For a complete discussion of menu mode, see Configuring Menu Mode on page
3-3.
8.9 Serial Port Configuration
There are a number of configurations that apply specifically to serial transmission. These configurations are
a port’s parity, baud rate, and bits per character. The bits per character is set using the Set/Define Ports
Character Size command, described on page 12-57. Set/Define Ports Parity (discussed on page 12-69)
sets a port’s parity, and Set/Define Ports Speed (discussed on page 12-79) sets the baud rate.
Note: Use of these commands is relatively straightforward. Please refer to the
designated page references for the appropriate syntax.
The Autobaud characteristic enables a port to detect an incoming baud rate, character size, and parity and
configure its characteristics to match. This characteristic cannot be enabled if the port’s Access is set to
Remote or Dynamic (see Setting Port Access on page 8-1) or if the specified port offers a service. To enable
Autobaud, use the Set/Define Ports Autobaud command, discussed on page 12-52.
The following sections discuss other configuration settings.
8.9.1 Naming a Port
To assign a particular name to a port, use the Set/Define Ports Name command.
Figure 8-30: Assigning a Port Name
The default name for each port is Port_n, where n denotes the port number (for example, Port_2).
