The modem does not beep.
If you hear beeps of any sort, those are known as BIOS beeps and they are designed to alert the user to a specific hardware problem.
Codes vary, according to the maker of the system and the BIOS installed for the motherboard (if custom-built).
I suggest that you take note of the number of beeps and check that against the documentation for your system/board...and see what the system is trying to tell you.http://www.google.com/search?hl=en&sou...oq=&aqi=g10
