We give you up to 5 accounts,is totally up to you. My modem is being used by another dial up networking connection or another program. Which includes fax software, operator programs, and call minder programs that may be using the modems COM port. You can view which programs are currently running on your computer by holding down the alt key then pushing the tab key on your computer keyboard. After all I do have a 33,600 modem installed.
Some people do have trouble getting a consistent connection.
Your connection is an analog circuit, unless you have a ISDN line installed.this is where the problem will be nine times out of 10. All Depends on how frozen it has become. If you can still move the mouse pointer around where are unable to work in a specific window, press Ctrl Alt Delete at the same time, and shut down the frozen application in the window which comes up. If you are unable to move even the malice and Control Alt Delete does nothing, then you will have to shut down your computer manually from the power switch. You can turn the computer bag 1 after a few minutes, and a problem should be gone.
