  • Finding resistance  
       The serial port is still a great tool in to computer industry today and will remain so for years to come because of its diverse capabilities.
       For example, there is a new race going on in the world of computers to come out with the next operating system for robotics and artificial intelligence technology, communicating through the serial port is one of the simplest ways of doing so. If you are creating a new life form, making a new computer mouse, or just troubleshooting a problem in a device, the information below is quite priceless.
