Introduction
This chapter provides a list of questions and answers for commonly asked questions about your
MultiModemISDN adapter. In the last part of this chapter you will find information about the “LINETEST” and
“LOG” utilities used for diagnosing ISDN line problems. If you are not able to resolve the issues after reading
this section, contact our Technical Support department (see Chapter 5 of this User Guide for more informa-
tion).
Frequently Asked Questions
Q: How can I get the driver version number?
A: In Win98, run HyperTerminal with a virtual modem connected to ISDN Com1 or 2, enter the
ATI to display the version number. You may also run LOG32.EXE to view the version number
(Version 2.21 or later). In Windows 2000, you may find the driver version by placing your
cursor over the LINKSTS icon on the task bar.
Q: How can I update the ISDN driver to a new version?
A: Download the latest ISDN PC adapter driver form Windows 98, NT and 2000 from our web
site at http://www.multitech.com. In Windows 98, run UPGRADE.EXE to update the driver
automatically, then reboot your system. In Windows NT, remove the existing driver, reboot
your system and install the new version. You will need to reconfigure the software for your
ISDN switch type.
Q: Why can’t I use HyperTerminal to dial? (Win 98 only)
A: Make sure HyperTerminal is configured with a virtual modem corresponding to the ISDN COM
port. If you do not have two virtual modems with ISDNCom ports added use
Start>Settings>Control Panel>Modems>Add. Select Have Disk and locate the proper file in
the modem subdirectory of the installation diskette.
Make sure the same protocol is used on both sides. Refer to the ATBn command (see Chap-
ter 3) to set up the correct protocol used on the B channel. ATI will display the current set-
tings.
Q: Why can’t I make a data connection through HyperTerminal? (Win 98 only)
A: Ensure the client and remote sides of the connection are using the same protocol to make a
data connection. You may use the ATBn command to set the protocol (refer to AT Commands
in Chapter 3 of this manual). Enter ATI to display information such as Software version
number, B channel protocol, connection speed, packet size, current MSN and current outgo-
ing phone number for billing.
Q: How can I monitor the ISDN line and make sure the ISDN card and line are working properly?
A: When the system boots up and invokes the ISDN driver, the driver will initialize the ISDN card
and selftest the IRQ, I/O, and chipsets. If you do not see any error messages, the ISDN card
and driver are working properly. In Windows 2000, you may run LINETEST.EXE to perform a
line test. It will ask you to enter an ISDN telephone and make a call. Enter a local number to
do a loopback test from your site to the ISDN switch. This will ensure the D and B channels
are working properly. Error messages 3301 and 3302 indicate a problem with the ISDN line.
Q: How can I enable Caller ID in HyperTerminal?
A: The driver does not display Caller ID as a default. If you want to enable Caller ID, enter the
command, AT#C1 and AT#C0. To disable Caller ID, enter AT#C? to give the current status of
Caller ID mode. This function is provided in Version 2.13 and later.
