Software Overview
The SLTALink Manager is a standalone application that can monitor a modem line,
answer an incoming phone call, associate the incoming call’s SLTA-10 Adapter (and
hence its network) with a LON device, and then launch a pre-determined application
for that particular network or SLTA-10 Adapter.
Combined with a properly designed
LNS host application, the SLTALink Manager lets a LONWORKS network establish a
connection to a remote PC through a pair of modems based on an event that occurs
locally to the network.
The SLTALink Manager provides a graphical user interface for creating, editing, and
diagnosing “links”. Each link represents a particular SLTA-10 Adapter and its
network. A link identifies several important aspects of the set-up, including the type
of connection (a remote connection via modems or a local, direct connection), the
COM port, the SLTA-10 Remote Identifier (see below), the baud rate of the serial
port on the SLTA-10 Adapter, and the dial-in password, if any. In addition, the link
indicates if a security callback is required and may be associated with a host
application. The link information is stored in a .slO file, located by default in the
c:\lonworks\bin\sltalO folder.
The SLTALink Manager application can associate a link with a LON device name
and then interface with the SLTA-10 NSI mode driver. The SLTALink Manager
handles automatically dialing into the network from the PC host, providing the
ability for applications with no knowledge of modems or phone numbers to run
remotely through a pair of modems.
The SLTALink Manager application can be used
to connect to or disconnect from a remote SLTA-10 Adapter.
In addition, the
SLTALink Manager has a simple, programmatic way to interact with the SLTA-NSI
mode. This programmatic interface allows an application to cause the SLTA-10 to
perform a number of functions, such as dial a phone number or hang up. The
SLTALink Manager also includes many diagnostic functions.
The SLTALink Manager includes many diagnostic functions.
NOTE: Remote SLTA-10 Adapters cannot be used with Windows NT 3.51 because
Windows NT 3.51 does not include the 3%bit TAPI services used by the SLTALink
Manager software.
Upon invocation of the SLTALink Manager software (SLTALINK . EXE), the main
screen appears, shown in figure 7.1.
