In telecommunications, the intercharacter interval is the time

Time

Time is a part of the measuring system used to sequence events, to compare the durations of events and the intervals between them, and to quantify rates of change such as the motions of objects....

 interval between the end of the stop signal

Stop signal

In telecommunication, the term stop signal has the following meanings:1. In asynchronous serial communication, a signal at the end of a character that prepares the receiving device for the reception of a subsequent character...

 of one character

Character (computing)

In computer and machine-based telecommunications terminology, a character is a unit of information that roughly corresponds to a grapheme, grapheme-like unit, or symbol, such as in an alphabet or syllabary in the written form of a natural language....

 and the beginning of the start signal

Start signal

In telecommunication, the term start signal:# A signal that prepares a device to receive data or to perform a function. Contrast with A-condition....

 of the next character of an asynchronous transmission

Asynchronous communication

In telecommunications, asynchronous communication is transmission of data without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream. Any timing required to recover data from the communication symbols is encoded within the symbols...

Note: The intercharacter interval may be of any duration. The signal sense of the intercharacter interval is always the same as the sense of the stop element, i.e., "1" or "mark."
