Methods
  NameDescription
Public methodAddWriteLogStream
Sets the stream to log the write data to.
(Inherited from ConnectionA.)
Public methodBytesAvailable
Returns an estimate of the number of bytes that can be read from this connection without blocking.
(Overrides ConnectionABytesAvailable.)
Public methodClose
Closes this connection and releases any system resources associated with the connection.
(Overrides ConnectionAClose.)
Public methodDispose

(Overrides ConnectionAReadChar.)
Public methodSendAndWaitForResponse(Byte, Int32, Int32, String)
Sends dataToSend and returns the response data.
(Inherited from ConnectionA.)
Public methodSendAndWaitForResponse(BinaryWriter, BinaryReader, Int32, Int32, String)

(Inherited from ConnectionA.)
Public methodSendAndWaitForValidResponse(Byte, Int32, Int32, ResponseValidator)
Sends dataToSend and returns the response data.
(Inherited from ConnectionA.)
Public methodSendAndWaitForValidResponse(BinaryWriter, BinaryReader, Int32, Int32, ResponseValidator)
Sends data from sourceStream and writes the response data to destinationStream.
(Inherited from ConnectionA.)
Public methodSetReadTimeout
Sets the underlying read timeout value.
(Inherited from ConnectionA.)
Public methodToString
Returns USB:[PrinterName].
(Overrides ConnectionAToString.)
Public methodWaitForData
Causes the currently executing thread to sleep until BytesAvailable > 0, or for a maximum of maxTimeout milliseconds.
(Inherited from ConnectionA.)
Public methodWrite(Byte)
Writes data.Length bytes from the specified byte array to this output stream.
(Inherited from ConnectionA.)
Public methodWrite(BinaryReader)
