==========================
You may encounter some problems or doubts while installing or using your
modem. This chapter highlights some of the more common issues concerning
your modem and their possible solutions. Reviewing this FAQ.txt can help
you solve many problems and often eliminate the need for telephone

01. Q: How to identify the MDP7800 modem and drivers?
A: The model of your card is printed on the serial number label
located at the rear of the modem card. For drivers, open the
readme.txt file and you will see the model MDP7800 being mentioned.
You can also issue an ATI5 command using any telephony Data terminal
application to get the driver version.
02. Q: Why does my modem always connecting at 33.6k but not 56k or V90?
A: Check with your ISP to ensure that they support K56Flex or V.90
connection. Make sure that your modem is using the 56k driver. For
modems with Country Selection feature, please ensure that the modem
is set to your local country. If you are still having problems,
please check with your ISP and their Central Site Modem's firmware.
03. Q: The system cannot detect the modem when I first inserted the card.
What's wrong?
A: Please make sure that the card is fully inserted into the PCI Bus.
If the system still cannot detect the modem, you may wish to try
using a different PCI slot instead. Refer to Easy Start Manual or
readme.txt for instructions on installation.
04. Q: How do I test that the modem is working properly?
A: Go to Start/Settings/Control Panel/Modem/Diagnostic
Select the Com Port that the modem is connected to and select More
Info. If the modem is working properly, a window will appear listing
all the AT Commands.
05. Q: I have done the Diagnostic test. However, the system gave an error
message that the system is unable to open the Com Port.
A: Make sure you have closed all communication software (Hyperterminal,
Dial-up Networking etc.) when you are doing the Diagnostic test.
However, if you are sure that you have closed all communication
software but the error persisted, do the following, Go to
Start/Settings/Control Panel/Systems. Check whether there is any
yellow exclamation mark on the modem section. If yes, remove them by
selecting the conflicting device, and click Remove. Remove all
conflicting devices and re-start the system. The system will detect
the modem and may prompt you for the driver. Please follow the
online instructions.
06. Q: 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?
A: 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.
