It is a good idea to unplug dialup modem and only plug it in if you need to use it. This is a safeguide incase a rogue dialer gets on your system. Dialers can't dial out via BB but will dial out via a connected dialup modem possibly without you knowing until phone bill arrives..
yep , i would agree that the modem should be connected into the pc direct .Another thing you could do is download the latest drivers for your modem . I had a problem with my modem and new drivers sorted it out . Good luck to you ,when you get going you'll find BB is worth every penny.
