Additionally, the sender must be configured to send 1, 1.5, or 2 stop bits at the end of each transmission. 1.5 and 2 stop bits were more widely used in the past to synchronize communication with ancient electromechanical devices. Nowadays, parity checks and stop bits greater than 1 are not needed for communications using modern transceivers and are rarely used.

This group of settings is often abbreviated into something such as 115200-8-N-1 or 38400-8-O-2 to indicate, respectively, a 115.2 Kbps serial line with 8 data bits per symbol, no parity and 1 stop bit, and a 38400 line with the same data bits, odd parity, and 2 stop bits.
