Questions tagged [baud-rate]

"baud-rate" refers to the number of signal or symbol changes that occur per unit time. This tag is for questions that get, set, or otherwise manipulate the baud rate.

In telecommunications and electronics, baud (/ˈbɔːd/, unit symbol "Bd") means symbols per second or pulses per second. A "symbol" being one of several voltage, frequency, or phase changes.

Thus a "baud-rate" refers to the number of signal or symbol changes that occur over time—most commonly per second. A baud rate differs from a bit-rate in that a single symbol transition (baud) can communicate more than one bit during the interval, whereas a bit rate is a single bit per interval.

This tag is OS and Language independent, as long as there's a mechanism for manipulating the serial data rate this tag can apply.

counting bits in a message sent over a serial port

I'm trying to figure out the bit rate of an attached serial device. I've configured the device to send binary data at a rate of 10Hz. My plan was to look at one message from the device, count the number of bits, and then multiply by 10 to get…
