baud

A unit of data transmission equal to 1 bit/sec. Technically, baud is the number of times/sec that the carrier signal shifts value—e.g., a 56k bit-per-second modem actually runs at 14.4 baud, but it moves 4 bits per baud. Named after a Emile Baudot 1845-1903, a French telegraph engineer, inventor of the Baudot code, and pioneer of telecommunication.

Vary the word length, stop bits, and baud rate until good transmission is achieved.
Features include a 9-24 VDC power range, switch-selectable baud rates from 9600 to 115.2K and LED indicators for power, transmit and receive.
The rate is $15 per hour (25 cents per minute) at 300 baud (about 30 characters per second) and twice as much for 1200 baud (about 120 characters per second).
Consider an application that samples an audio input at 8 kHz using a 10 bit ADC that converts the sampled audio to mu-law encoding (8 bits, used in telephone communications) and transmits this via an RS-232 serial line at 115,200 baud, as well as processing the audio signal and driving a VU meter showing current audio level.

"If you take an (ISDN) terminal and compare it to a typical phone with a 9600 baud modem and two phone lines, it comes out within less than $100 difference."
* A programmable baud rate from 4,800 to 115,000 baud.
Used with proprietary virtual COM port (VCP) drivers, the USB NMC provides inter-PC,COM port-based communication at up to 3M baud rates.
