The Settings tab of the modem tag properties folder contains properties that allow you to configure the network and security settings for the modem tag.

The Workstation Name field enables you to specify the name of the computer to which the modem is connected. If you do not specify a workstation in the Workstation Name field, VTS will use a local modem on a machine that is running that tag within the application, selecting the first modem that is available.
Note: Once the workstation name has been specified, the Line Name and Name Or Index On Workstation drop-down lists will automatically update to display the names of the serial port tags and modems available on this workstation.
The Line Name drop-down list enables you to select the name of an existing phone line to which this modem is attached, or enter a new and unique line name to which this modem is attached. This name must be unique, and cannot be identified anywhere else in the system.
The same line name must be used by modems sharing the same physical phone line, even if they are on different workstations.
The Name Or Index On Workstation drop-down list enables you to select a modem on the workstation specified in the Workstation Name field, provided that the workstation is available. If the specified workstation is not currently available, you may enter the name of the modem you wish to use, or can enter a number or text value as follows:
If this value is numeric, it is the index into the list of modems shown in the Modems Properties dialog box in the Windows Control Panel, starting from 1.
If the value of Index is a text string, it is the name of the modem exactly as it appears in the Modems Properties dialog that is accessed using the Windows Control Panel.
Note: Because the index of available modems can change over time, it is recommended that you refer to the modem by name rather than by its index in the Modem Properties dialog box.
The Ring Count spin box enables you to select the number of rings you wish to occur before the selected modem answers an incoming call.
If the value of Ring Count is 0, the modem will not answer any calls.
Note: Irrespective of this setting, the modem will not be answered if the Config.ini [SYSTEM] variable, AnswerCalls is set to 0. (Information on the configuration variables pertaining to the Modem Manager can be found in "VTS Programmer's Guide: Config.ini [SYSTEM] Section Settings for the Modem Manager".)
The Security Bit drop-down list enables you to select an existing application-specific privilege that will restrict output access for this tag. Users who wish to use this tag to send an outgoing signal to the I/O device or modem must have the privilege by which this tag is protected granted to their user account.
If the Security Bit drop-down list is left blank, there is no security specified for the tag.
Application privileges are added using the Administrative Settings security dialog. Information on creating application privileges can be found in Add Application Privileges Using the Administrative Settings Dialog.
