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.

Linux read, write Arduino serial

I'm trying to write to an Arduino serial from a c++ program. How do I set the baudrate in the C++ program? The communication seems to work, when the arduino is set to 9600, but fails when I change it, as expected.(so 9600 is the default?) Using the…

Non-standard serial baud rate of 62,500 on a PC

I am looking for a way of using a baud rate of 62,500 (8N1) on a windows PC on a serial port or USB->serial adapter to communicate with an older piece of hardware that uses this speed. Can this be done via code or is it a hardware solution?

Baud rate of IP network

Since all the devices on the internet talks without a presetting of the baud rate, it seems all of them should have the same baud rate. If so what is the baud rate of devices communicating over internet protocol?
