The BinaryReader and BinaryWriter classes support reading and writing data in

a variety of formats, including bytes and other numeric types, Boolean data,

Chars, and length-prefixed strings.

An application uses the SerialPort object’s BaseStream property to obtain a

Stream object and then uses the object to create BinaryReader and Binary-

Wr i t e r o b j e c t s :

 Friend binaryReader1 As BinaryReader
Friend binaryWriter1 As BinaryWriter
Dim serialPortStream As Stream

' Get the port's Stream object.

serialPortStream = myComPort.BaseStream

' Use the Stream object to create BinaryReader and BinaryWriter objects.

binaryReader1 = New BinaryReader(serialPortStream)

binaryWriter1 = New BinaryWriter(serialPortStream)

 internal BinaryReader binaryReader1;
internal BinaryWriter binaryWriter1;
Stream serialPortStream = null;

// Get the port's Stream object.

serialPortStream = myComPort.BaseStream;

// Use the Stream object to create BinaryReader and BinaryWriter objects.

binaryReader1 = new BinaryReader( serialPortStream );

binaryWriter1 = new BinaryWriter( serialPortStream );

The Write method can write a byte to a port:

 Dim dataToWrite As Byte

dataToWrite = 65

binaryWriter1.Write(dataToWrite)
