UART Flow Control is a method for slow and fast devices to communicate with each other over UART without the risk of losing data.
a) “Cloud Service” means the enablement of certain functionality of the Software through the use of cloud services provided by Intel through a third party. In this example, we use PuTTY SSH Client that is available for both Windows and Linux. You can use other serial programs and set communication parameters like below. ENTIRE AGREEMENT; SEVERABILITY. The terms and conditions of this Agreement and any NDA with Intel constitute the entire agreement between the parties with respect to the subject matter hereof, and merge and supersede all prior or contemporaneous agreements, understandings, negotiations and discussions. Neither Party will be bound by any terms, conditions, definitions, warranties, understandings, or representations with respect to the subject matter hereof other than as expressly provided herein. In the event any provision of this Agreement is unenforceable or invalid under any applicable law or applicable court decision, such unenforceability or invalidity will not render this Agreement unenforceable or invalid as a whole, instead such provision will be changed and interpreted so as to best accomplish the objectives of such provision within legal limits.

f) “Intel Data” means all aggregate information, raw data, analytics and data created, derived or generated in any manner from or by the Software or Cloud Services during Your, Your employees, contractors, or end users use of Software or the Cloud Services but does not include Customer Data. When sending data over USB, we use Serial. This data can be viewed in the Serial Monitor in the Arduino IDE. In the most common settings of 8 data bits, no parity and 1 stop bit (aka 8N1), the protocol efficiency is 80%. For comparison, Ethernet's protocol efficiency when using maximum throughput frames with payload of 1500 bytes is up to 95% and up to 99% with 9000 byte jumbo frames. However due to Ethernet's protocol overhead and minimum payload size of 42 bytes, if small messages of one or a few bytes are to be sent, Ethernet's protocol efficiency drops much lower than the UART's 8N1 constant efficiency of 80%. Byte receive buffer and 128 Byte transmit buffer utilizing buffer smoothing technology to allow for high data throughput.

Background of USB Communication
As seen in the image above when using parallel communication an 8-bit message would require eight cables while serial communication only requires one cable for sending messages and one for receiving. Dual, Quad and Octal 66MHz PCI bus UARTs with Power Management Support, 16C550 compatible register set, 64-byte TX and RX FIFOs with level counters and programmable trigger levels, Fractional baud rate generator, Automatic RTS/CTS or DTR/DSR hardware flow control with programmable hysteresis, Automatic Xon/Xoff software flow control, RS-485 half duplex direction control output with selectable turn-around delay, Infrared (IrDA1.0) data encoder/decoder, Programmable data rate with prescaler. DataSheets are dated from 2008 and 2010. NO OBLIGATION; NO AGENCY. Intel may make changes to the Software, or items referenced therein, at any time without notice. Intel is not obligated to support, update, provide training for, or develop any further version of the Software or to grant any license thereto. No agency, franchise, partnership, joint-venture, or employee-employer relationship is intended or created by this Agreement.
