Appendix A — Frequently Asked Questions
I have done a diagnostic of the modem and that’s nothing
wrong with it. However, when I use a communication
application, there seems to be an error, why?
Try to use a different telephony application like Microsoft Fax to fax
a document. If the fax is successful, then the fax function for the card
is working fine.
For Data connection, try to use Hyperterminal to dial up to a BBS. If
the connection is successful, then the data function for the cards is
working fine as well.
You may try to install new versions of communication software that
supports higher interrupts.
How do I remove the old modem drivers installed in the
system?
Run “deinstal.exe” in the MDP7800 modem installation CD to
uninstall MDP7800 modem drivers.
What is the maximum speed that this modem supports and
whose solution is this card using?
The MDP7800 modem supports up to 56kbps. It is also backward
compatible with most of the old standards. The MDP7800 uses
Lucent 56k chipset solution.
Is this modem upgradable to ITU V.90 56k standard?
Yes. No hardware upgrading is required. This is a V.90 ready
modem. You may also visit our website to get the latest updates on
the release timing for the updated drivers.
