Proper noun
RS-232
(telecommunications, computing) Recommended Standard 232; the standard for serial binary signals between a DTE and a DCE.
An application program can detect or change the state of RS-232 control lines in the registers of the serial hardware using only a few input/output instructions; by contrast, a USB interface requires software to decode the serial data. Source: Internet
An RS-232 serial port can communicate to some embedded systems such as routers as an alternative to network mode of monitoring. Source: Internet
Because both ends of the RS-232 circuit depend on the ground pin being zero volts, problems will occur when connecting machinery and computers where the voltage between the ground pin on one end, and the ground pin on the other is not zero. Source: Internet
At the time, most personal computers had asynchronous RS-232 serial ports for data communications between the computer and devices such as modems. Source: Internet
An RS-232 serial port was optional on the original versions of the Model 4. The keyboard had a control key, a CAPS lock key, and three function keys. Source: Internet
Connectors RS-232 devices may be classified as Data Terminal Equipment (DTE) or Data Circuit-terminating Equipment (DCE); this defines at each device which wires will be sending and receiving each signal. Source: Internet
