The Arduino has only one UART which is used for program upload and for the serial terminal output to your computer. While you can connect it to another serial device that will make debugging cumbersome as 1) you won't be able to send any debug output; and 2) you will need to change it back and forth between your computer and the GPRS as you re-build and upload your code.It is both a RS232 shield and also a RS485 Shield for Arduino. It can easily convert UART to RS232 or RS485 interface. The shield integrates DB9 connectors (female) that provide connection to various devices with RS232 interface and also provide a RS485 screw terminal interface.From the Groups list under Target hardware resources, select Serial port properties. The Serial 1 baud rate parameter is set to 9600. In this example, the baud rate of Serial 1 baud rate is set because the TX1 and RX1 pins correspond to the Serial port 1 of the Arduino hardware. If you are using any other serial port pins for communication, specify the baud rate of the corresponding serial port. Atmel AT89S51/52 microcontroller has an integrated UART module for carrying serial communication. Serial communication makes use of asynchronous mode of operation. Serial port is defined as an interface between the PC and a device for transfer of data. AT89S51/52 with a serial port will allow reading and writing values to and from computer. The Arduino IDE uses it to upload our programs to the board but the serial connection can also be used for any other kind of communication. Arduino also has digital pins 0 (RX) and 1 (TX) which can be used to directly connect Serial interfaced wires into Arduino. They deliver the same signals sent on the USB Serial interface. Hello forum, I have my Arduino UNO pumping out serial messages. I have a USB Serial UART connect on another port.
