I mean it in the sense of at the hardware level--one complete frame which is often the payload plus any overhead. Here is a more complete and accurate explanation: What is the difference between baud rate and bit rate? | |
| May 12, 2021 at 0:36 | comment | added | C. M. | That is not entirely correct, either. Baud is the rate it transmits one complete unit of data--which can be 8-bits, or even 7-, 9- or 10-bits, depending on era and if it includes a parity bit, checksum bit, and so on. | |

| May 11, 2021 at 22:06 | comment | added | alejandro mendoza | thanks you give me the correct answer, I'm setting the serial port speed to 9600 and this is the baudrate and i was measuring the bit time with the oscilloscope, and I was confused because early modems used to transmit only 1 bit per baud but it is because it is "packing" 8 bits into each baud | |
| May 10, 2021 at 19:59 | comment | added | C. M. | Baud rates are not the same as clock speed (baud is also not the same as bits per second, either!). Look up the terms and how they apply to serial communications. Then, if you still have issues/concerns, edit your question appropriately so you are NOT comparing incompatible terms. | |
