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.

SAM. Driver For Winxp. gov The System for Award Management (SAM) is the Official U.S. Government system that consolidated the capabilities of CCR/FedReg, ORCA, and EPLS. Jul 20, 2015. Dim returnStr As String = '. Determine which serial port should provide the strings. This example assumes it is COM1. Use the My.Computer.Ports.OpenSerialPort method to obtain a reference to the port. For more information, see OpenSerialPort. The Try.Catch.Finally block allows the application to.

All code that manipulates the serial port should appear within this block or within a Try.Catch.Finally block. The method sends the data to the serial port. Sub SendSerialData(ByVal data As String) ' Send strings to a serial port. 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. 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.
