    <p>I need to write some byte to the serial connection. However I can not find something in <a href="http://code.google.com/p/java-simple-serial-connector/" rel="nofollow">JSSC</a> library to set a write timeout. I need this timeout because if I set the hardware flowcontrol and I remove the cable my application is stuck waiting the CTS signal.</p> <p><strong>UPDATE</strong></p> <p>I tried this workaround with Future object:</p> <pre><code> ExecutorService executor = Executors.newSingleThreadExecutor(); ... public synchronized void write(byte[] content, int timeout) throws InterruptedException, SerialPortException{ long starttime = System.currentTimeMillis(); Future&lt;Boolean&gt; future = executor.submit(new Callable&lt;Boolean&gt;() { public Boolean call() throws Exception { serialPort.writeBytes(content); return new Boolean(true); } }); try { future.get(timeout, TimeUnit.MILLISECONDS); log.debug("Duration: {}",DurationFormatUtils.formatDuration(System.currentTimeMillis() - starttime, "mm:ss.SS")); } catch (ExecutionException e) { throw new HardwareException(e.getMessage()); } catch (TimeoutException e) { throw new HardwareException("Impossibile scrivere nella porta seriale (timeout)"); } } </code></pre> <p>But it doesn't work very well, it take 4s to write 550byte via COM port 256000 baud...</p> <p>Trying a direct write:</p> <pre><code> public synchronized void write(byte[] content, int timeout) throws InterruptedException, SerialPortException{ try { long starttime = System.currentTimeMillis(); serialPort.writeBytes(content); log.debug("Duration: {}",DurationFormatUtils.formatDuration(System.currentTimeMillis() - starttime, "mm:ss.SS")); } catch (SerialPortException e) { throw new HardwareException(e.getMessage()); } } </code></pre> <p>It took 0.5s as expected!</p> <p>The problem seems to be the "syncronized" keyword in the main method, why?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
