How to: Send Strings to Serial Ports in Visual Basic • • 2 minutes to read • Contributors • • • • • • In this article This topic describes how to use My.Computer.Ports to send strings to the computer's serial ports in Visual Basic. Example This example sends a string to the COM1 serial port. You may need to use a different serial port on your computer. Use the My.Computer.Ports.OpenSerialPort method to obtain a reference to the port.

For more information, see. The Using block allows the application to close the serial port even if it generates an exception. All code that manipulates the serial port should appear within this block or within a Try.Catch.Finally block.

Using com1 As IO.Ports.SerialPort = My.Computer.Ports.OpenSerialPort('COM1') com1.WriteLine(data) End Using End Sub Compiling the Code • This example assumes the computer is using COM1.

Library for use of COM objects in PureBasic, an example for using the ADODB object for accessing. Sending and receiving of data through the serial port. PureBasic - SerialPort example file;; (c) Fantaisie Software;; -----; CompilerIf #PB_Compiler_OS = #PB_OS_Windows Port$ = 'COM1' CompilerElse Port$ = '/dev/ttyS0.

Robust Programming This example assumes the computer is using COM1; for more flexibility, the code should allow the user to select the desired serial port from a list of available ports. For more information, see. This example uses a Using block to make sure that the application closes the port even if it throws an exception.

OpenSerialPort OpenSerialPort() Syntax Result = OpenSerialPort(#SerialPort, SerialPortName$, Bauds, Parity, Data, Stop.f, HandshakeMode, InputBufferSize, OutputBufferSize) Description Opens a serial port for use. Parameters #SerialPort A number to identify the new serial port. Can be used to auto-generate this number. SerialPortName$ Text identifier for the serial port, for example 'COM1' on Windows or '/dev/ttyS0' on Linux.

Bauds Defines the speed of the serial connection and can be one of the following values: 50, 75, 110, 150, 300, 600, 1200, 1800, 2400 4800, 9600, 19200, 38400, 57600 or 115200 Parity Defines how the parity will be handled on the connection. It can be one of the following values: #PB_SerialPort_NoParity: No parity #PB_SerialPort_EvenParity: Even parity #PB_SerialPort_MarkParity: Mark parity #PB_SerialPort_OddParity: Odd parity #PB_SerialPort_SpaceParity: Space parity Data Defines the data length, in byte (usually 7 or 8). Stop Sets the number of stop bits (1, 1.5 or 2). HandshakeMode The handshake mode.

It can be one of the following values: #PB_SerialPort_NoHandshake: No handshaking #PB_SerialPort_RtsHandshake: No handshaking but RTS is set to 1 #PB_SerialPort_RtsCtsHandshake: RTS/CTS #PB_SerialPort_XonXoffHandshake: Xon/Xoff InputBufferSize Defines the size of the input buffer, in bytes. OutputBufferSize Defines the size of the output buffer, in bytes. Return value Nonzero if the serial port was successfully opened, zero otherwise (it may be already in use, or the parameters are wrong).
