Appendix C - Applications
This appendix provides an introduction to popular applications that can be utilized with your ISDN TA adapter.
TRUMPET Setup through COM Port Emulation
In Windows 95 and Windows 98, the virtual COM port driver will automatically be enabled on system startup
through Microsofts Windows Comm. API (VCOMM).
Microsoft HyperTerminal
HyperTerminal was designed for Microsoft by Hilgraeve Inc. and is provided with Windows 98, Windows NT
and Windows 2000. The program provides a simple set of communication tools to make getting on-line easy.
HyperTerminal can also be used to obtain diagnostic information from your modem after a session with your
ISP or to make test calls to an ISP.
If you are trying to use the HyperTerminal for a point to point connection, youll need to set up a virtual modem
attached to your ISDN ComPort. Please refer to Chapter 2 for more information on setting up an ISDN
connection for a virtual modem for your operating system. Whether you use the ISDN (X.75 Transparent, 64K)
adapter modems or universal modems, to use the X.75 protocol, you must include the ATB3n command in the
Advanced Connection Settings screen as shown below.

At the receiving site, enter ATS0=1 to automatically answer incoming calls. Note that the default protocol in
the B channel is HDLC 64K with packet size 2048. If you would like to change the B channel protocol use the
following steps.
Go to extra setting field : Start>Settings>Control panel>Modems>Properties>
Connection>Advanced>Extra settings.
You can improve reliability and performance by changing the packet size for the B channel to 512 bytes.
Change this setting permanently by entering ATS39 = 512 in the Extra Setting field. If you would like the B
channel protocol, packet or Window size to be reset to default values when the application is finished, you may
input these values manually. For example, to select a X.75 Transparent with 1024 packet size for B channel
connection use, ATB30S45=1024.
