Microsoft HyperTerminal
HyperTerminal was designed for Microsoft by Hilgraeve Inc. and is provided with Windows
95, 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 a BBS or an ISP.
If you are trying to use the HyperTerminal for a point to point or BBS connection, you’ll 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.
Figure C-2. HyperTerminal for Point to Point or BBS Connection
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.
