In telecommunications, RS-232 or Recommended Standard 232 [1] is a standard originally introduced in 1960 [2] for serial communication transmission of data. It formally defines signals connecting between a DTE ( data terminal equipment ) such as a computer terminal or PC , and a DCE ( data circuit-terminating equipment or data communication ...

A timing diagram can contain many rows, usually one of them being the clock. It is a tool commonly used in digital electronics, hardware debugging, and digital communications. Besides providing an overall description of the timing relationships, the digital timing diagram can help find and diagnose digital logic hazards .
SPI timing diagram for both clock polarities and phases. Data bits output on blue lines if CPHA=0, or on red lines if CPHA=1, and sample on opposite-colored lines. Numbers identify data bits. Z indicates high impedance. The SPI timing diagram shown is further described below: CPOL represents the polarity of the clock.
IRIG standard 212-00 defines a different time-code, based on RS-232-style asynchronous serial communication. The timecode consists of ASCII characters, each transmitted as 10 bits: 1 start bit; 7 data bits; 1 odd parity bit; 1 stop bit; The on-time marker is the leading edge of the first start bit.
Mark and space symbols (current directions in early telegraphy, later voltage polarities in EIA RS-232 and so on, frequency-shift polarities in frequency-shift keying and so on) Asynchronous start-stop signaling was widely used for dial-up modem access to time-sharing computers and BBS systems.
