Rollover cable (also known as Cisco console cable or a Yost cable) is a type of null-modem cable that is often used to connect a computer terminal to a router's console port. This cable is typically flat (and has a light blue color) to help distinguish it from other types of network cabling. It gets the name rollover because the pinouts on one end are reversed from the other, as if the wire had been rolled over and you were viewing it from the other side.
This cabling system was invented to eliminate the differences in RS-232 wiring systems. Any two RS-232 systems can be directly connected by a standard rollover cable and a standard connector. For legacy equipment, an adapter is permanently attached to the legacy port.
