Serial Ports: Difference between revisions

Serial ports are a legacy communications port which has pretty much been succeeded by [[USB]] and other modern communications technology. However, it is much easier to program than USB, and it is still found in a lot of computers (especially older ones such as the ones the financially limited amateur OS writer might use for [[Testing|testing]]). Also, a lot of phone modems (which are still used to access the Internet quite often, even though broadband is very accessible and affordable) connect via the serial interface. Furthermore, it is possible to use the serial ports for debugging, since a lot of emulators allow the redirection of their output into a file.
