BluetoothSerialPort explain DSR / DTR? BluetoothSerialPortListener dataReceived() does not block?

Hello

Two questions please.

Can someone please shead light on what DSR / DTR is, what about the Bluetooth? In the BluetoothDemo.SSPScreen, there are 3 menu items: "Get DB", "DSR on", "off DSR. What are these for and why I would DSR on or off?

During the implementation of BluetoothSerialPortListener, the method dataReceived don't block until the method ends, or only up to _port.read (buf, 0, 1024))! = 0) has finished loading the buffer of bytes? Then playback of NEMA sentences of a washer that some data are seen as corrupt, so we we ask who has the fault it is this.developer, or the washer? I need to create a logic of blocking until all of the method is completed?

Thank you in advance.

Profile of Serial Port Bluetooth emulates a serial port wired.  DB corresponds to the DTR line on a serial port (of wired type, no Bluetooth).  We have no documentation on that to provide it is not specific to the BlackBerry or Bluetooth, so you can learn more on this subject in the General documentation of serial port.

The BluetoothSerialPortListener.dataReceived method is triggered when the data are arrived at the BlackBerry, passing in the length data is available to be read.  Your application can read up to the size specified in the length, but should not block, waiting for more data.  When more data is available the method should the new fire.  Please take a look at the BluetoothSample provided with the BlackBerry JDE for an example.

    How can I make sure that any firewalls (versions of software or hardware) does not block port 443 to access?

    Hi Anna_753,

    Usually, you would receive messages from any program if it is impossible to access the port.

    If you want to check if the port is accessible, then you will need to check the firewall settings.

    Each firewall has its own parameters for ports of the computer.

  • Smartphones from blackBerry Bold 9900 stole, but it does not block the service provider

    Hello

    My phone got stolen, but it does not block the service provider. All they did was disable the sim card.

    BlackBerry protect now cant work because the phone cannot connect to the network.

    Don't know what else to do

    It is each carrier as they will blacklist the device or simply to block the SIM card.  The good news is that no one can rack up charges on your account using your old phone.  Now when you get a new, open a BlackBerry Protect session and cancel the old phone.  You can then connect your new phone and restore your contacts.

    I hope that helps you.

  • G50-30 Windows 8 parental does not block websites

    I just bought a laptop Lenovo G50-30 for my child, but after that I set up with parental controls, I discovered that Microsoft's parental control blocks all websites on my child's account. I tried to create multiple children accounts; I tried to create an account for local child; I tried the factory reset. and I tried troubleshooting Microsoft fix. None of them solved the problem. My assumption is that a third-party program is breaking the parental control of Microsoft, but I can't know which program is the cause. I uninstalled Mcafee and disabled other programs to run, but it does not solve the problem. A that someone has experienced this problem and found a solution?

    For someone who is interested, I discovered that McAfee LiveSafe has a parental control feature Family Safety of this Microsoft ignores. Once I enabled it worked fine. I didn't use good McAfee and I had previously uninstalled without solving the problem, so this time I tried to uninstall it and then ran McAfee product removal tool and then parental control of Microsoft has worked well.

  • Even though I have my Windows Mail spam set to the highest level, I continue to receive unwanted emails. For some reason any Windows Mail does not block them. How can I fix it?

    I have my blocker spam Windows Mail, the highest value which means I should only receive emails from my contacts.  Despite this, I continue to receive unwanted emails.  This has been so since I've upgraded to Windows 7.  I even went now install a machine program washing 'spam' which was a disaster as well.  I get about 4-5 spam emails a day - usually when I start the morning.

    How can I solve this problem?

    What Windows Mail in Vista or Windows Live Mail in Win7? If it is a POP3 account, you can filter your messages by using message rules. This is for Outlook Express, but it works the same either of the programs.

    Start with the only rule of AddressBook and you receive a message that you want people not in your address book (E-mail from companies, bills, your ISP, etc), you can add them to the rule.

    Box 1 - Where the From line contains people {check it out}

    Box 2 - Check: delete it & stop processing more rules if you want messages not in the address book to go to deleted items, or you can create a spam folder and direct them here.

    You can choose to delete the server, but be careful because you never have messages downloaded to any folder, if you choose this option.

    Box 3 - Click on the blue words contains people

    Click on the first address to select it. Scroll to the end and hold down the SHIFT key while you click the last address. This will highlight all. Right-click on it and click on from the menu that appears.

    Now, click Options and choose: Message * contains no of * the people below in the top of the page Options area, then choose: Message corresponds to one of the people below in the background Options box.

    OK your way out of the new rule.

    Now, only the addresses that you entered will be uploaded to your Inbox. You won't see other emails.

    Remember, if you add a person to your address book, you must add to the rule. It will not automatically be added.

    Be sure to see these links for more options.

  • datagramconnection/messageconnection receive() does not block?

    Hi, I wrote a SMS using JDE4.7 listener, the listener is in its own thread.  This runs in the simulators for 9530 (OS4.7), 8310 (OS4.5) and 8330 (OS4.3) seems to be very good.  However, when deploying on a live device, it seems work correctly for the 9530 (asbl, 4.7.0.75).

    I have attached the live 8310 (att, OS4.5.0.110) and 8330 (asbl, OS4.3.0.127) to my debugger, and when starting the listening thread, the connection.receive () method does not seem to hang at all, it returns immediately with a "String index out of range:-2" exception.  I have also compiled this same code under JDE4.3, which does not seem to make a difference.

    In which case it is important, the 9530 and 8330 are on BIS, the 8310 is on BES with rather strict policies.

    I tried both types of connections below, the two work very well for the 9530, but these two don't for curves. Any help would be appreciated, I've been hitting my head against the wall for the last 2 weeks trying to find a solution.

    dgConnection = (DatagramConnection)Connector.open("sms://:0");
    Datagram datagram = dgConnection.newDatagram( dgConnection.getMaximumLength() );
    dgConnection.receive( datagram );
    String address = new String( datagram.getAddress() );
    dgConnection.close();
    
    msgConnection = (MessageConnection)Connector.open("sms://:0");
    Message message = msgConnection.receive();
    String address = message.getAddress();
    msgConnection.close();
    

    I saw this, and I think that the exception that you receive is the result of a bug in the firewall application. He tries to instantiate a "Permissions" dialog box so that the user can approve the use of the SMS port.

    Check the permissions of application for your device - I bet that 'phone' is set to 'request' or 'decline '. Change to 'Allow' and your problem should go away.

  • Router firewall does not block traffic

    Hello

    I use vmware view Home 4.6 client.  I can authenticate and connect to a windows image 7, but only a black screen appears.  After about 30 seconds it disconnects with the error "the connection to the remote computer has ended."

    If I disable my billion router firewall, the machine virtual windows 7 appears and everything works as expected.  I tried port forwarding 4172 and 5002 but still does not work.  Then I tried port forwarding 50000 to 65000 I saw various 50456 to 64652 ports in firewall logs.  TCP and UDP are enabled in both cases, but no luck.

    Here is the part of the firewall log:

    04 August 23:01:38 home.gateway:firewall:info: 476378.910 blocked Prot = 17, 192.168.1.1:56143 > 10.100.200.1:137 - default defense

    04 August 23:01:38 home.gateway:firewall:info: 476378.910 blocked Prot = 17, 192.168.1.1:52771 > 10.100.200.1:137 - default defense

    04 August 23:01:38 home.gateway:firewall:info: 476378.910 blocked Prot = 17, 192.168.1.1:64632 > 10.100.200.1:137 - default defense

    192.168.1.1 is my computer and 10.100.200.1 is my domain controller from work.

    I then tried to create a packet filtering rule to allow 4172, then 50000 to 65000, but nothing worked.  To disable the firewall of the router or select the parameter of low security for her is the only way to operate.  The default medium security setting blocks the traffic.

    Router is a VGP 7301 billion.  Any advice would be much appreciated.  Thank you.

    Hello

    Im sorry im not familiar with this particular modem however I got something similar on my draytek at home. Mine to connect for a few seconds, and then stop working.

    I discovered that it was because my BACK settings on my modem have been set to protect against a stream of UDP. I was able to disable then part of security BACK settings and then it worked ok.

    Maybe it's the little, you have problems with that. I have no port forwarding on my configuration, and im sure I wasn't leaving the installation rules, all incoming traffic is blocked.

    I hope this helps.

    See you soon

    [Edit]

    Just checked, I 32111 outgoing tcp (redirect usb) and also 4172 TCP/UDP outgoing (pcoip). Nothing, nothing allowed incoming traffic.

  • Why Firefox continues to block all the content I want to see, including tickets, I want to buy out my favorite despite changes sites does not block content?

    the program continues to block the content even with blocking function disabled. I constantly switch between browsers due to the annoying feature. I want it to stop blocking content, I want to disable the blocking, but laboriously must stop at all the sites I visit and spend time while it blocks content, demand if I want to keep the content blocking, annoyingly sinks and I must say to "remember" not to do and does it continuously , while continually annoyingly content blocks! I want him to stop doing that. I'm an adult, I'm 60 years old. I don't need a babysitter on my browser telling me what I should see and what I see, please fix this as soon as possible. Apparently disable the pop-up blocker does nothing to stop this annoying problem. Its design and its content filtering. It's illegal I think since my content I pay and I pay view all content on the world wide web. I want to stop my research of filtering and blocking content! ENOUGH!

    You have an extension, the FindWide toolbar, which many view as an unwanted intruder. You should be able to disable or remove the page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click Extensions.

    For completeness, here's my method to track down and clean up bad Add - ons and other ad injectors. I know it seems long, but it's not so bad.

    (1) open the Control Panel, uninstall a program. After the loading of the list, click on the column heading "installed on" to group infections, I mean additions by date. This can help the undisclosed items bundle smoker who snuck out with some software, you have agreed to install. Beware of everything that you don't recognize / remember, since malware often uses sounding names important or innocent to discourage you remove. Out as much garbage as possible here.

    (2) open Firefox page modules using either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons
    • in the Windows "Run" dialog box, type or paste
      firefox.exe "about:addons"

    In the left column, click on Plugins. Set essential and unrecognized plugins 'never enable '.

    In the left column, click Extensions. Then, in case of doubt, disable (or delete, if possible) not recognized and unwanted extensions.

    Often, a link will appear above at least an extension disabled to restart Firefox. You can complete your work on the tab and click one of the links in the last step.

    Any improvement?

    (3) you can search the rest of problems with scanning/cleaning tools listed in our technical support article: Troubleshooting Firefox problems caused by malware. These scanners on request are free and take a long time to run. If they end quickly, especially if they require the payment you have a serious infection. I suggest the specialty forums listed in the article in this case.

  • Why is so slow Safari and does not block pop-ups?

    Just typing this message was an exercise in patience.  I constantly get the bouncing ball waiting to continue typing.

    My Prefs 'Block Windows blocker' checked and yet, any Web site I visit, I constantly put in place with the videos pop up.  This behavior happened in the last months.

    I use V9.1.2 (11601.7.7).

    Thank you.

    OK, I went through the suggestion of TextWrangler and found that my code was exactly the dough - in host code, so I just left it as it was.  Also, I followed the suggestion of Wacom driver and deleted my Wacom tablet driver for good measure.

    Bottom line

    I think I see a slight improvement, but as I started to type this post I once more facing the bouncing ball and wait to continue typing.  On the pages Web that are long Safari blocks always upwards, but not as bad as it was before the removal of the driver.  Other tests of page Web reveals that the pages will continue to freeze without getting the bouncing ball.

    It's all very annoying and I am not sure that I made real improvements to this problem.  Time will tell, I guess.

    Thank you!
