  • I would also disagree with not seeing baud rates faster than 115.2Kbps. DMX-512A, the RS-485 serial protocol used for theatrical lighting control, runs at 250Kbps. Atmel AVR UARTs are capable of 2Mbps while some PICmicro UARTs are capable of 8Mbps.

  • ******Correction: In line>> we’re actually sending 9600 bits per second or 960 (9600/10) bytes per second. it should be 960 (9600/10) data bytes per second. right? correct me if I am wrong.

  • How does this work without using CTS and RTS handshaking?

  • A nice primer, was hoping to learn a bit more, but mostly it's stuff I've already dealt with.

    I would argue that RS-232 isn't nearly as unused as you imply. It gets used a lot in industrial and retail systems. For instance we have Serial connections on a large number of our machines for connecting to large scales and electronic tag readers.

  • Its nice. Generally, parallel needs eight wires, one for each bit of the data so that whole 8 bits are send at the similar time. This interface utilizing 25 pin connector, & is extra of a printer version.

    You can get more information about it.

  • This was really awesome, it cleared up so much for me in such a short amount of time. It was clear and entertaining. I loved the "cross the streams reference". :)

  • Thanks for making this! This is the clear overview of serial communication that I've wanted for YEARS! It really helped me connect the dots and understand what is happening in serial communication. This will help me in my implementation of serial transmissions!
