Line 17:

A general rule is that DCE devices provide the clock signal (internal clocking) and the DTE device synchronizes on the provided clock (external clocking). [[D-sub]] connectors follow another rule for pin assignment. DTE devices usually transmit on pin connector number 2 and receive on pin connector number 3. DCE devices are just the opposite: pin connector number 2 receives and pin connector number 3 transmits the signals.

When two devices, that are both DTE or both DCE, must be connected together without a modem or a similar media translator between them, a [[crossover cable]] must be used, e.g. a [[null modem]] for RS-232<!--<ref>[http://www.svbug.com/developer/documentation/articles/serial-uart/#AEN96]</ref>--> or an [[Ethernet]] crossover cable.
