Appendix A Frequently Asked Questions
I have done a diagnostics test of my modem and there is nothing
wrong with it. However, when I use a communications software, there
seems to be an error. Why?
Windows 95/98/NT 4.0
Try to use a different telephony application like
Microsoft Fax
to fax a
document. If the sending of a fax is successful, then the fax function of your
modem is working fine.
Try to use
Hyperterminal
to dial up to a BBS. If the connection is successful,
then the data function of your modem is working fine.
Try exiting the communications software and running it again.
While testing the modem, the system gave an error message saying
that it was unable to open the COM Port.
Make sure that you have closed all communication software (e.g.
Hyperterminal, Dial-up Networking, etc.) when you are doing the diagnostics
test.
However, if there is no communications software running, do the following:
1. From the Windows taskbar, click
Start
>
Settings
>
Control Panel
.
2. Double-click the
System
icon.
3. Click the
Device Manager
tab.
4. Check whether there is any
yellow exclamation mark on
the modem device. If yes,
remove the modem device and
re-install the modem drivers.
