> We only had one phone line and the downside of this for my parents was that no-one could call the house phone - engaged tone. I bought this little box on ebay that monitored for the call waiting signal while dialup was connected and then let the call ring through. If I was quick I could get starcraft to reconnect when a telemarketer interrupted. It was a lot cheaper than a second phone line!
