Solving audio, multimedia, and modem problems
Can’t use second modem
If your computer came with more than one modem or 
if you added a second modem:
•
Make sure that the telephone line is connected to the 
modem you want to use.
•
Make sure that the communications software you are 
using is properly configured to use the second 
modem. If your computer came from the factory with 
a second modem, Line 2 is for Data/Fax only. You will 
be unable to use voice or video conferencing features 
with the Line 2 modem.
•
Make sure that the second modem is properly 
configured. A second modem must use a different 
COM port and system IRQ from the first modem.
When you try to use the 
modem, your computer or 
modem is unable to detect 
a dial tone
