Name | Description | |
---|---|---|
Address |
Returns the address which was passed into the constructor.
| |
Connected |
Returns true if the connection is open.
(Inherited from ConnectionA.) | |
Manufacturer |
See the classes which implement this property for the format of the printer manufacturer string.
(Inherited from ConnectionA.) | |
MaxDataToWrite |
Gets or sets the maximum number of bytes to write at one time
(Inherited from ConnectionA.) | |
MaxTimeoutForRead |
Gets or sets the maximum time, in milliseconds, to wait for any data to be received.
(Inherited from ConnectionA.) | |
PortNumber |

Gets or sets the maximum time, in milliseconds, to wait in-between reads after the initial read.
(Inherited from ConnectionA.) |
Name | Description | |
---|---|---|
AddWriteLogStream |
Sets the stream to log the write data to.
(Inherited from ConnectionA.) | |
BytesAvailable |
Returns an estimate of the number of bytes that can be read from this connection without blocking.
(Overrides ConnectionABytesAvailable.) | |
Close |
Closes this connection and releases any system resources associated with the connection.
(Inherited from ConnectionA.) | |
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) | |
GetConnectionReestablisher |
Returns a ConnectionReestablisher which allows for easy recreation of a connection which may have been closed.
(Overrides ConnectionAGetConnectionReestablisher(Int64).) | |
GetHashCode | Serves as the default hash function. (Inherited from Object.) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
Open |
Opens the connection to a device.
(Inherited from ConnectionA.) | |
Read |
Reads all the available data from the connection. This call is non-blocking.
(Inherited from ConnectionA.) | |
Read(Int32) |
Reads maxBytesToRead of the available data from the connection.
(Inherited from ConnectionA.) | |
Read(BinaryWriter) |
Reads all the available data from the connection.
(Inherited from ConnectionA.) | |
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.
(Inherited from ConnectionA.) | |
SendAndWaitForResponse(Byte, Int32, Int32, String) |
Sends dataToSend and returns the response data.
(Inherited from ConnectionA.) | |
SendAndWaitForResponse(BinaryWriter, BinaryReader, Int32, Int32, String) |
Sends data from sourceStream and writes the response data to destinationStream.
(Inherited from ConnectionA.) | |
SendAndWaitForValidResponse(Byte, Int32, Int32, ResponseValidator) |
Sends dataToSend and returns the response data.
(Inherited from ConnectionA.) | |
SendAndWaitForValidResponse(BinaryWriter, BinaryReader, Int32, Int32, ResponseValidator) |
Sends data from sourceStream and writes the response data to destinationStream.
(Inherited from ConnectionA.) | |
SetReadTimeout |
Sets the read timeout on the underlying socket.
(Overrides ConnectionASetReadTimeout(Int32).) | |
ToString |
Returns TCP:[Address]:[PortNumber].
(Overrides ConnectionAToString.) | |
WaitForData |
Causes the currently executing thread to sleep until BytesAvailable > 0, or for a maximum of
maxTimeout milliseconds.
(Inherited from ConnectionA.) | |
Write(Byte) |
Writes data.Length bytes from the specified byte array to this output stream.
(Inherited from ConnectionA.) | |
Write(BinaryReader) |
Writes all available bytes from the data source to this output stream.
(Inherited from ConnectionA.) | |
Write(Byte, Int32, Int32) |
Writes length bytes from data starting at offset.
(Inherited from ConnectionA.) |
