1. Load the direct connect project and then double-click on the Channel Name. This will invoke the current direct
connect settings for Baud Rate, Parity and etc.
2. Select the Use Modem checkbox. The settings on this page should now become unavailable.
3. Next, click on the Modem tab to display the list of modems available on the computer.
Note: If there are no modems visible on list, users will need to exit the server and attempt to reinstall the modem
using the Modem Configuration tools supplied with the operating system.
4. Select the modem that will be used with the server project. At this point, the Dialing... and Properties... buttons
should become available. Select Properties...
Note: The Properties dialog is used to configure the initiating modem's characteristics. There are two sections available:
 General is used to set connection speed and speaker volume. The connection speed should be set to match the
speed used by the target device when this was a direct connect project.
 Connection is used to configure Data Bits, Parity and Stop Bits. These settings should be set to match the target
device settings.
5. Next, click the Advanced... button.
Note: The Advanced Connection dialog is used to configure error correction and flow control for the initiating
modem. For more information about recommended settings, refer to the specific driver's help documentation. In most
cases, Error Correction and Data Compression can be enabled; Flow Control can be either enabled or disabled,
depending.
6. Next, click OK in each dialog until returned to the modem list within the server. When editing an existing project,
users can click OK. When editing a new project, users can click Next. If, at this point, an existing direct connect project
has just been edited, the server project is now ready for modem operation.
7. Save the project.
Using a Modem in Your Application
Once modem operation has been enabled for the driver, a list of predefined tags became available in the driver's Tag
Window. These Modem Tags are contained under the Channel Name, which has become an active OPC Access path used
to access the Modem Tags. The Modem Tags are used to control and monitor an attached modem. Operationally, the
server knows very little about what the application needs for modem control; thus, the server does not imply any type
of control over it. By using the predefined Modem Tags, users can apply the application's control or scripting capabilities
to control the server's use of the selected modem.
Phonebook Tags
A Phonebook Tag can be used in place of specifying a telephone number by directly writing to the PhoneNumber tag. A
phonebook tag can be created on the channel, along with the other modem system tags previously described. The data
associated with a Phonebook tag is a phone number that can be assigned when the tag is created and/or later modified
when the server has an active client connection. The phone number stored in a phonebook tag can be used to dial by
simply writing anything to the tag. The act of writing will cause the selected phonebook tag to dial.
Syntax Example: <Channel Name>._Phonebook.<Phonebook Tag Name>
