[[Image:Serial cable (blue).jpg|thumb|Serial cables are typically used for [[RS-232]] communication.]]<br />
A '''serial cable''' or '''RS-232 cable''' is a [[electrical cable|cable]] used to transfer information between two devices using a [[serial communication]] protocol. The form of connectors depends on the particular [[serial port]] used. A cable wired for connecting two [[data terminal equipment|DTE]]s directly is known as a [[null modem]] cable.<br />
<br />
==Maximum cable lengths==<br />
The maximum working length of a cable varies depending on the characteristics of the transmitters and receivers, the [[baud rate]] on the cable, and the [[capacitance]] and [[electrical impedance]] of the cable. The [[RS-232]] standard states that a compliant port must provide defined signal characteristics for a capacitive load of {{val|2500}} pF. This does not correspond to a fixed length of cable since varying cables have different characteristics. Empirically tested combinations of bit rate, serial ports, cable type, and lengths may provide reliable communications, but generally RS-232-compatible ports are intended to be connected by, at the most, a few tens of metres of cable. Other serial communications standards are better adapted to drive hundreds or thousands of metres of cable.<br />
