I have a project in which i draw in drawing and same thing is drawn in glcd. Through serial communication, byte[] buffer_2_send = new byte[1]; byte data_2_send = 0; data_2_send = Byte.Parse(textBox2.Text);//this way you will get the value 12 in your variable //we will use a buffer because the serial_port.Write takes either a string or a buffer of data buffer_2_send[0] = data_2_send; MessageBox.Show(“” + buffer_2_send + ” ” + buffer_2_send.Length); serialPort1.Write(buffer_2_send, 0, buffer_2_send.Length); i basicaly send 12 or like this values on microcontroller but at recieving side i cant recieve respective value so plz guide me. If you have an application that writes to a serial port device through a USB adapter, and the application is hard-coded to use COM port 5, is there anything you can do so that moving a laptop that uses this application from one docking station to another will NOT cause Windows Plug and Play to assign a different COM port based on the VID of the second USB-to-serial device being different from the VID of the first USB-to- serial adapter? The docking stations both use the same peripherals, all plugged into the same USB ports. The users of these laptops don’t have administrative rights to change the COM port in Device Manager. Some USB-to-serial adapters advertise ‘COM port retention’, but that only seems to make the laptop use the same COM port for the exact same USB-to-serial adapter (the very same one, not just one that ‘seems’ the same but has a different VID) each time the laptop is connected to that device.

Communicate-Over-Serial-Port-In-PHP.zip (1.2 kB). We will use this extension for serial port communication. SSI Protocol employs and provides only a single channel. A typical hardware setup using two to form an inter-chip To begin communication, the bus master configures the clock, using a frequency supported by the slave device, typically up. I did this once with Debian to control an Arduino board with a PHP script and initially ran into the same problem. In Debian, you need to add the Apache user to the dialout group in order to allow it to make serial connection requests.
