This serial interface, found on older PCs, is often referred to as UART (the transmitter-receiver itself) or RS-232 (the protocol). Throughout most of the history of personal computers, data was transferred through serial ports to devices such as modems, terminals, and various peripherals. A regular RS-232 Cable (make sure it is not a null modem cable, they look the same). Once a standard feature on personal computers, the RS232 serial port was one of the first used to connect data terminals to mainframe computers. Historically, RS232 Communication protocol is an old serial communication protocol developed by EIA (Electronics Industry Alliance)/TIA (Telecommunications Industry Association)-232 in the year 1962. You'll have to shift those signals!. comm, though other than the change in package name the API follows the Java Communication API. Also make sure to close the Arduino serial monitor before you try talking to it from your program. Some sensors off er serial output as the only interface. RS 232 is well-known due to popularity of today's PC's. To obtain data from your RS232 instruments and display it on your PC you need some software. Modern hardware designs use innovative serial communication protocols like USB, Ethernet, and Wi-Fi. DTE stands for Data Terminal Equipment. BytesToRead And maybe look into setting a lower than default timeout on the serial read. It is called asynchronous because there is no separate synchronizing clock signal as there are in other serial protocols like SPI and I2C. Post by MrSwiss » Feb 19, 2016 8:54.
