The number of bytes or characters sent over the phone lines in 1 second. [Abbreviated as CPS].

A measure of the rate at which data is transferred or printed by a printer.

A data transfer rate generally estimated from the bit rate and the character length. For example, at 2400 bps, 8-bit characters with start/stop bits (for a total of ten bits per character) will be transmitted at a rate of approximately 240 characters per second (CPS). Some protocols, such as error-control protocols, employ advanced techniques such as longer transmission frames and data compression to increase CPS.

This is the number of characters that can be sent over the phone lines in 1 second.
