Not all bit rates are possible with all serial ports. Some special-purpose protocols such as MIDI for musical instrument control, use serial data rates other than the teleprinter series. Some serial port systems can automatically detect the bit rate. The speed includes bits for framing stop bits, parity, etc. This is 16 times the fastest bit rate and the serial port circuit can easily divide this down to lower frequencies as required.

The number of data bits in each character can be 5 for Baudot code , 6 rarely used , 7 for true ASCII , 8 for most kinds of data, as this size matches the size of a byte , or 9 rarely used. Most serial communications designs send the data bits within each byte LSB least significant bit first. This standard is also referred to as "little endian.

The order of bits is not usually configurable within the serial port interface. To communicate with systems that require a different bit ordering than the local default, local software can re-order the bits within each byte just before sending and just after receiving. Parity is a method of detecting errors in transmission. When parity is used with a serial port, an extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even. If a byte is received with the wrong number of 1s, then it must have been corrupted.

However, an even number of errors can pass the parity check. Electromechanical teleprinters were arranged to print a special character when received data contained a parity error, to allow detection of messages damaged by line noise. A single parity bit does not allow implementation of error correction on each character, and communication protocols working over serial data links will have higher-level mechanisms to ensure data validity and request retransmission of data that has been incorrectly received.

Aside from uncommon applications that use the last bit usually the 9th for some form of addressing or special signaling, mark or space parity is uncommon, as it adds no error detection information. Odd parity is more useful than even, since it ensures that at least one state transition occurs in each character, which makes it more reliable. The most common parity setting, however, is "none", with error detection handled by a communication protocol.

Stop bits sent at the end of every character allow the receiving signal hardware to detect the end of a character and to resynchronise with the character stream. Electronic devices usually use one stop bit. If slow electromechanical teleprinters are used, one-and-one half or two stop bits are required. This specifies 8 data bits, no parity, 1 stop bit. In this notation, the parity bit is not included in the data bits.

In many circumstances a transmitter might be able to send data faster than the receiver is able to process it. To cope with this, serial lines often incorporate a " handshaking " method, usually distinguished between hardware and software handshaking. Generally, the RTS and CTS are turned off and on from alternate ends to control data flow, for instance when a buffer is almost full. DTR and DSR are usually on all the time and, per the RS standard and its successors, are used to signal from each end that the other equipment is actually present and powered-up.

However, manufacturers have over the years built many devices that implemented non-standard variations on the standard, for example, printers that use DTR as flow control. The XON and XOFF characters are sent by the receiver to the sender to control when the sender will send data, that is, these characters go in the opposite direction to the data being sent. The circuit starts in the "sending allowed" state.

When the receiver's buffers approach capacity, the receiver sends the XOFF character to tell the sender to stop sending data. Later, after the receiver has emptied its buffers, it sends an XON character to tell the sender to resume transmission. It is an example of in-band signaling , where control information is sent over the same channel as its data.

The advantage of hardware handshaking is that it can be extremely fast; it doesn't impose any particular meaning such as ASCII on the transferred data; and it is stateless. Its disadvantage is that it requires more hardware and cabling, and these must be compatible at both ends. The advantage of software handshaking is that it can be done with absent or incompatible hardware handshaking circuits and cabling. The disadvantage, common to all in-band control signaling, is that it introduces complexities in ensuring that a control messages get through even when data messages are blocked, and b data can never be mistaken for control signals.

The former is normally dealt with by the operating system or device driver; the latter normally by ensuring that control codes are " escaped " such as in the Kermit protocol or omitted by design such as in ANSI terminal control. If no handshaking is employed, an overrun receiver might simply fail to receive data from the transmitter.

Approaches for preventing this include reducing the speed of the connection so that the receiver can always keep up; increasing the size of buffers so it can keep up averaged over a longer time; using delays after time-consuming operations e.
