dialup connection availability

i want to know user can connect via dialup or it has no dialupmodem and it uses permanent internet connection like cable or dsl. best method is looking to modem devices. if any dialup modem installed on pc, it can connect via dialup. any other ideas? your software will look at dialup modems and it reports any modem installed or not. software will be written in delphi and easy to use. i will use that code in my another software. Note: Code will be very small and after compile, it will be smallest size. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Exclusive and complete copyrights to all work purchased.
