| Read(Int32, Boolean) |
Reads maxBytesToRead of the available data from the connection.
(Inherited from ConnectionA.) |
| ReadChar |
Reads the next byte of data from the connection.
(Overrides ConnectionAReadChar.) |
| SendAndWaitForResponse(Byte, Int32, Int32, String) |
Sends dataToSend and returns the response data.
(Inherited from ConnectionA.) |
| SendAndWaitForResponse(BinaryWriter, BinaryReader, Int32, Int32, String) |
