Installation
The ISDN LOG application is used to record the handshaking and data transfer
process during communication. It can be used for debugging purposes so it is
useful to have the log running while first starting to use the ISDN system. The
Line Diagnostic is used for on-line channel testing between the ISDN switch
and subscriber site, and getting ISDN line status. Please refer to Chapter 4 for
detailed information.
5. You can re-configure the parameters of step 3 by executing the ISDN Configur-
er in the ISDN Group Folder. The Configuration dialog box also displays the
I/O address and IRQ value in the message bar.
2.5 Application Interface Setup
Under Windows 3.x applications, you can configure your terminal adapter device
using either COM port emulation, the standard WinISDN interface, or the CAPI
2.0 interface.
1. COM Port Emulation. The ISDN driver provides AT command set interpreter
to emulate modems and transfer/receive data through the ISDN network. You
must set up your application software to the appropriate COM ports (COM3 or
COM4) to communicate with the ISDN adapter. The AT Console program
(see Figure 2-5) can redirect the AT commands and data through COM3 or
COM4 to the ISDN driver to process them.
If you want to set up an Internet connection through COM port emulation,
TRUMPET is a popular Internet shareware and includes the TCP/IP and PPP
protocols with Winsock interface. Many Windows 3.1 Internet modems use
TRUMPET to connect to the Internet and to run Internet applications such as
Netscape Navigator. TRUMPET users should modify the Network Configuration
and Script files to access the Internet through terminal adapters. See Appendix B
for an example of a setup modification for TRUMPET.
When entering Windows 3.1, you must run the AT Console to enable the COM
port emulation capability.
Multilink PPP is not supported at the AT Console. You may get a Multilink
PPP connection through the applications which include a TCP/IP and Multilink
PPP stack with WinISDN or CAPI interface.
