What is a smartcp modem?

What is SmartCP?SmartCP in simple terms is a computer modem feature or function. Some modems have this function built directly into it's firmware. (i.e. "PCI Soft Data Fax Modem with SmartCP"). What SmartCP does:

The purpose of SmartCP is to allow the modem to resume retrieving or downloading large files should the connection or download become interrupted and or disconnected. Instead of wasting valuable time downloading the portion you have received before the transfer was interrupted, SmartCP transparently continues the download from the last know good point. Anyone who has spent many hours or even days downloading a file only to find that they have been disconnected with only 99% of file received knows the thought of all time in anticipation going to waste makes SmartCP a welcome addition to the modem.

Prior to SmartCP less than successful attempts were made to solve the 'resume download' problem via software and software protocols. Lack of a proper industry standard meant that many sites, services and software packages were either incompatible with each other or did not support the option at all.
