In asynchronous data transmission, the non-data bits (one or two) that the sending device transmits after each seven or eight-bit character code, enable the receiving device to recognize the end of each character.
A term used in serial data transfer to distinguish where one character starts and another stops; communication programs normally add one, or sometimes two, stop bits on the end of each character. Like data bits, it is important that the number of stop bits set up agrees at both ends of the line.
A voltage level used to signal the end of a character transmission frame.
Because asynchronous communications use no clock to regulate a transmission, start bits and stop bits are used to signal the beginning and end of a byte.
In data communication, one or two bits used to mark the end of a byte (or character). At least one stop bit is always sent.
Used to indicate the end of each character as it is transmitted.
During data transfer, 1 or 2 extra bits may be added onto the end of each character by the RS232 interface so that the receiving equipment can detect the end of the character. These are the stop bits and, depending on the quiescent state of the line, may be 0's or 1's. The generation of the stop bits at the sender and then their removal at the receiving equipment, is totally transparent to the user and is carried out by the RS232 interfaces.
A bit that signals the end of a character. One of the serial communications parameters.
A sequence of bits sent by a device transmitting data so that the device receiving the data can synchronize its clock, which dictates the intervals at which individual bits are expected to be sent and received.
