About ModemDoctor

ModemDoctor dates back to 1988 and was the first of a series of diagnostic tools that helped PC users troubleshoot and configure serial ports and modems. Although serial ports are rapidly becoming "old technology", there still are a fair number of them and modems in use.

ModemDoctor is just one of a line of shareware supported products that are (and will be) available here. In the coming months, new products and updates to old will emerge, along with other user-informative info. We are re-launching slowly and appreciate your visiting our site.
