[Turn] Calculation serial baud rate

115200 = 115200 baud rate (bits / sec).

If no parity bit, it should be divided by 10 to obtain the number of bytes per second: 115200 = 115200 baud rate (bits / sec) = 11,520 (bytes / sec).

Divided by 1024, KB per second is: 115200 = 115200 baud rate (bits / sec) = 11.25 (KB / sec). If there is a parity bit , it should be divided by 11 to obtain the number of bytes per second.

We came to the conclusion: 115200 = 115200 baud rate (bits / sec) = 10.27 (KB / sec).

Extended Information

 

Sometimes in conjunction with confusion baud bit rate, which in fact is a measure of the transmission rate information (signaling ratio). The baud rate may be understood as the number of symbols of the transmission symbol unit time (transmission symbol rate), can be supported on a plurality of bits of information in one symbol by a different modulation method.

Generally it refers to the baud rate of the modem communication speed. The baud rate is the number of line status change. Only when each signal line with one of the transmitted data, it is equal to the number of bits per second.

For communication between each other, using the same baud modem must operate. If the modem baud rate is set higher than other modem baud rate of the modem is generally faster to change the baud rate to match the slower modem.

Strictly speaking, the transmission baud rate is not in the field, there is a transmission channel other words create confusion, the baud rate is the ability to describe the modulation signal per unit time, it is modulated by the signal coming out only in the form of bits to transmit, or Thus, the signal during transmission, if you want to go through digital-analog conversion, modulation requires, then the transmission time consumed in addition to other areas, but also consumed in the modulation process and a transmission channel, the signal modulation capability described baud , describe the signal transmission capability of bits.
