3. Network Variable Control 21
Request Dial String (Output)
C Language Syntax
network output SNVT_char_ascii nvoReqDialStr1;
network output SNVT_char_ascii nvoReqDialStr2;
Usage

This output network variable is associated with Perpetual Dial-Up Mode (see Tutorial
“Which Modem Mode Should Be Used” in section “2.
S ETUP AND O PERATION
”) and is used
when the Directory Object storing the telephone number (to be dialed) belongs to a node
other than the call-originating NCB.
Valid Range
0-F (Hex)
When Transmitted
Transmitted when the Modem Controller Object senses that a connection is not made.
Perpetual Dial-up Mode
The NCB module can be configured to provide a “perpetual” connection using the ‘dial-up’ mode
of the modem, with no runtime user or application intervention required to initiate or maintain a
constant modem connection.
There are two methods available for implementing a “perpetual” connection using Dial-up mode:
1) The first method uses only configuration properties. This method is useful when the Directory
Object storing the telephone number (to be dialed) belongs to the dialing NCB module.
a) Specify an entry in an NCB units Directory that contains the phone number to be dialed.
This can be accomplished using either the NCB/Plug Configuration Plug-in (discussed in
“Section 4. ” or using the “Dial Mode” Configuration Property (discussed later in this
section).
b) Set the “Dial Mode” (for the call-originating NCB) to “Perpetual”. This can be
accomplished most easily with the NCB/Plug Configuration Plug-in (discussed in
“Section “4. ” by accessing Dial Mode choices under the Modem Options menu item.
Changing the Dial Mode to Perpetual may also be accomplished by using the “Dial
Mode” Configuration Property (discussed later in this section).
2) The second method uses a combination of configuration properties and network variable
bindings. This method is useful when the Directory Object storing the telephone number (to
be dialed) belongs to a node other than the call-originating NCB.
a) Specify an entry in an NCB units Directory that contains the phone number to be dialed.
This can be accomplished using either the NCB/Plug Configuration Plug-in (discussed in
“Section 4. ” or using the “Dial Mode” Configuration Property (discussed later in this
section). This step is the same as in the first method.
b) Set the “Dial Mode” to “Manual” mode (the default setting).
c) Make network variable bindings as shown in Figure 8.
