Yes, by "internal modem" I am referring to 20 year old dial-up technology. Here in the states and overseas, there's a lot of supermarkets that have not gotten their stores on network. The problem is when I plug the phone line into my "old" laptop, it kills the DSL internet and I cannot dial out. The only way to make it work is to pull the power on the DSL modem\router. But that is very counter productive as I also need the internet connection while connected to a site.
