Object, Single, UInt32, UInt64. yes WriteLine Same as Write but with NewLine appended. NewLine only. yes For applications that transfer text, numeric data other than bytes, and logical values, the SerialPort class includes methods that handle the encoding and decoding of these data types. For example, an application that wants to send the text “CMD1” followed by a LF character could store the character codes in a byte array and write the array to a port: vb Dim dataToSend 4 As Byte dataToSend O = Asc "C" dataToSend l = Asc "M" dataToSend 2 = Asc 'D" dataToSend 3 = Asc T dataToSend 4 = 10 myComPort.Write dataToSend, 0, 5 164 Using .NET’s SerialPort Class Table 9-2: Applications have many choices when reading from a SerialPort object.
