SerNimpl ( Frame4J -- the Java framework de.frame4j... )

java.lang.Object
- java.io.InputStream
- - de.weAut.ioPorts.SerNimpl

All Implemented Interfaces:

SerialDefs, Closeable, AutoCloseable
```
public class SerNimpl
extends InputStream
implements SerialDefs
```
Serial input and output (by native implementation).

The input and output over the computer's serial (standard, V.24, RS232 etc. pp.) interfaces is most efficiently implemented by JNI (native methods).

The similarities to javax.comm respectively RXTX go as far as their habits are compatible to the implemented interface SerialDefs. Otherwise this class sticks to usual operating system habits as procured by the used class WinDoesIt.

The SerNimpl object is (itself) a InputStream, allowing (in the ready state) the reading of bytes or byte arrays from the serial interface.

An OutputStream allowing the writing of bytes or byte arrays to the serial interface is provided (as object of an anonymous inner class) by the method getOut() (in the ready state). But, the three write() methods as well as close() should be called as directly provided by this SerNimpl object, except where an OutputStream object is explicitly needed.

  - getPortName
```
public final String getPortName()
```
    Description copied from interface: SerialDefs
    
    The used interface's name.
    
    It will be platform dependent: something like "COM1", "COM2", "serialA" etc.
    
    Specified by:
    
    getPortName in interface SerialDefs
    
    Returns:
    
    the port's name
  - getPort
```
public long getPort()
```
    The serial port's number (handle).
    
    The returned valid handle (if applicable) will be used (at least in the Windows implementation WinDoesIt) internally for all further operations on the respective port.
    
    For (very) special applications that port (as its number / handle) is made available by this method.
    
    Hint: This goes (far) beyond the type SerialDefs's contract.
    
    Hint 2: Until July 2013 this was an int. 64 bit Windows 64 bit made the "handle" type a long (without any evident need for the range).
    
    Returns:
    
    Handle to the port used; on Windows it is a (pseudo) file handle
  - openSerial
```
public void openSerial(CharSequence comPort)
                throws IOException
```
    Connect to a serial port of given name.
    
    This SerNimpl respectively SerialDefs object will be connected to the serial port named comPort.
    
    Any failure will be signalled by an IOException.
    
    Hint: On Windows the serial ports' names are usually "COM1", "COM2" and so on; and they are case-insensitive.
    
    Specified by:
    
    openSerial in interface SerialDefs
    
    Parameters:
    
    comPort - Portname (null or empty returns null without Exception)
    
    Throws:
    
    IOException - file or stream problem

  - getRcvTimeout
```
public int getRcvTimeout()
```
    Description copied from interface: SerialDefs
    
    The serial ports's receive timeout in ms.
    
    On receive timeout's (rcvTimeout) values > 0 reading methods return after that time in ms (milliseconds) independent of having received any bytes.
    
    Specified by:
    
    getRcvTimeout in interface SerialDefs
    
    Returns:
    
    the current receive timeout in ms
    
    See Also:
    
    SerialDefs.setRcvTimeout(int)
  - setSerialTimeouts
```
public boolean setSerialTimeouts(int readIntervalTimeout,
                                 int readTotalTimeoutMultiplier,
                                 int readTotalTimeoutConstant,
                                 int writeTotalTimeoutMultiplier,
                                 int writeTotalTimeoutConstant)
```
    Set the serial port's timeouts.
    
    readIntervalTimeout:
    Maximum time in milliseconds before the arrival of a second and all following bytes.
    A value -1 (interpreted by the driver as a very big unsigned value) combined with two times 0 for the next two values will provide immediate return with buffered input valued, even that may mean none at all.
    
    readTotalTimeoutMultiplier:
    Factor in milliseconds for the whole read operations timeout. This value will be multiplied by the maximum number of bytes expected (length of input buffer provided).
    
    readTotalTimeoutConstant:
    This value will be added to the product just described. If both are 0 that means no timeout for read operations.
    
    writeTotalTimeoutMultiplier:
    Factor in milliseconds for the whole write operations timeout. This value will be multiplied by the number of bytes to be written (length of output buffer / array provided).
    
    writeTotalTimeoutConstant:
    This value will be added to the product just described. If both are 0 that means no timeout for write operations.
    
    Remark:
    If readIntervalTimeout and readTotalTimeoutMultiplier are -1 (meaning unsigned maximum) and readTotalTimeoutConstant is > 0 and < (unsigned) maximum, the following applies:
    If there is at least one byte (or more) in a system (driver) or hardware input buffer, the read operations will return immediately fetching values from that buffer.
    If the buffer is empty, the read operations will wait for the first byte input and fetch it.
    If no input byte arrives within readTotalTimeoutConstant a timeout occurs.
    
    Parameters:
    
    readIntervalTimeout - between the bytes (see above)
    
    readTotalTimeoutMultiplier - * number of bytes (see above)
    
    readTotalTimeoutConstant - + (see above)
    
    writeTotalTimeoutMultiplier - * number of bytes (see above)
    
    writeTotalTimeoutConstant - + (see above)
    
    Returns:
    
    true bei Erfolg

```
public void setRcvTimeout(int rcvTimeout)
```

    Returns:
    
    the port's actual parity setting

public boolean setSerialPortParams(int baudrate,
                                   int dataBits,
                                   int stopBits,
                                   int parity)
```
    Description copied from interface: SerialDefs
    
    Set all relevant parameters of the serial port.
    
    This method sets (almost) all parameters relevant for the port's communication protocol in one step. The set of parameters is that the station at the other and of the line must have set the same way to enable any communication.
    
    A value -1 means no change of the setting in each case.
    
    baud rate:
    Sensible values are only the usual rates, i.e. 9600 (usual default), 19200, 38400 and so on.
    
    Implementations should evaluate the values 0..12 as index to the usual baud rates:
    110, 150, 300, 600, 1200, 2400, 4800, 9600, 19200, [0 .. 8]
    28800, 38400, 57600 and 115200 [9 .. 12].
    
    parity:
    Here only the relevant PARITY_x (x= NONE, ODD, EVEN, MARK and SPACE), like SerialDefs.PARITY_NONE (default), make sense.
    
    dataBits:
    Here only the relevant constant values DATABITS_x (x=5..8), like DATABITS_8 (default), make sense. They are the values 5..8.
    
    stopBits:
    Here only the relevant constant values STOPBITS_x (x=1, 2 or 1_5), like SerialDefs.STOPBITS_1 (default), make sense.
    sinnvoll.
    
    Hint 1:
    Implementations are free (and often recommended), to let all other setters delegate to this method and to let only this method really talk to the underlying hardware / platform.
    
    Hint 2:
    In the case of successfully calling the the hardware / driver / platform, implementations may re-read the actual setting and signal discrepancies (by returning false) as error. This proceeding is strongly recommended as some drivers silently accept standard baud rates or data widths they can't handle and replace them (silently) by some default or previous value.
    
    Specified by:
    
    setSerialPortParams in interface SerialDefs
    
    Parameters:
    
    baudrate - the baudrate to be set
    
    dataBits - the data item width to be set
    
    stopBits - the number of stop bits to beset
    
    parity - the parity to be set
    
    Returns:
    
    true on successful change or if already set so; false on any error or rejection. In the case of false, nevertheless, changes may have taken place.

    If not ready or if b is null nothing happens at all.
    
    Implementations shall delegate (in case of b not null} to write(b, 0, b.length).
    
    Specified by:
    
    write in interface SerialDefs
    
    Returns:
    
    -1 on failure or not ready, otherwise the number of bytes written; that will be = b.length on total success
  - write
```
public boolean write(int b)
```
    Description copied from interface: SerialDefs
    
    Write one byte to the serial port.
    
    If not ready nothing happens at all.
    
    Specified by:
    
    write in interface SerialDefs
    
    Returns:
    
    true on success
  - flush
```
public boolean flush()
```
    Empty the (system's) output buffer.
    
    The output buffers will be flushed.
    
    Hint: There are no useful informations on necessity and return behaviour for serial interfaces from platform specification. It should be not to naive, to infer that bytes fed to a USART or its driver will flow out by itself as fast as hardware and receiving station permit.
    This method (i.e. the method provided native by the platform) called often or may be at all will probably make no sense.
    
    Returns:
    
    true on success

    WinDoesIt.flushSerial(long)
  - purgeSerial
```
public boolean purgeSerial(int ops)
```
    Get rid of pending operations.
    
    It is quite usual to call this method with the OR of all PURGE constants after opening.
    
    Parameters:
    
    ops - One or more (OR) PURGE constants
    
    Returns:
    
    true bei Erfolg
    
    See Also:

  - getOut
```
public OutputStream getOut()
```
    Fetching the OutputStream.
    
    Only in case of a ready port this method provides the "out direction" as stream. close() of the port or of that OutputStream invalidate both.
    
    Hint 1: The OutputStream object mainly delegates to the "direct" SerNimpl respectively SerialDefs write methods. They should be used directly as far as possible. In other words, this method should not be called, except in cases where an OutputStream object is needed explicitly and unavoidably.
    
    Hint 2: If an InputStream is needed, this SerNimpl object (itself) is it.
    
    Hint 3: Repeated calls return the same OutputStream object, as long as the serial port stays ready.
    
    Returns:
    
    A fitting OutputStream or null
  - getExMsg
```
public String getExMsg()
```
    Description copied from interface: SerialDefs
    
    The last exception's message.
    
    If an operation failed by an exception, this method will deliver the explaining error text.
    
    The same event shall be "explained" only once. Implementations shall clear that text after the first delivery.
    
    Hint: Concurrent (multi-thread) use of serial ports is strongly discouraged anyway.
    
    Specified by:
    
    getExMsg in interface SerialDefs
    
    Returns:
    
    explaining error text or null
  - toString
```
public String toString()
```
    Text representation.
    
    The interface's state will be given as a (may be multi-line) text.
    
    If an error is pending according to the method's getExMsg() criteria, its explanation will be part of the status text returned.
    
    Specified by:
    
    toString in interface SerialDefs
    
    Overrides:
    
    toString in class Object
  - toString
```
public StringBuilder toString(StringBuilder bastel)
```
    Text representation.
    
    The interface's state will be given as a (may be multi-line) text.
    
    If an error is pending according to the method's getExMsg() criteria, its explanation will be part of the status text returned.
    
    Parameters:
    
    bastel - the StringBuilder to append to. If null, it will be generated with starting capacity 180.
    
    Returns:
    
    bastel
