Unstable signal given during the RS232 connection to PC

• How to keep the RS232 connection

  Hello everyone. I have a problem with the RS232 communication. To activate the connection, I need to send the string "RS232", then the keep alive I send every second CR, but in the meantime, I have to be able to send any other strings without delay on the same port (COM7). Can someone help me?

  Thank you

  RS232 standard does not impose itself to be kept alive in some way, so I guess that's your remote device that requires it.

  In any case, you could create a timer of 1 s and having his reminder send periodically the CR on the serial port.

  To avoid conflicts between this task and in the rest of the application, you can use a lock: basically, after you have created the lock, each function that wants to access the serial port must call CmtGetLock (), work on the port and call CmtReleaseLock () afterwards. If the lock belongs to another function, other functions when trying to get access are frozen waits for the lock, so you must be careful in the design of COM function so that they are quick. If you do not want to have a function be blocked waiting for the lock, you can use CmtTryToGetLock instead of CmtGetLock. You will find some information about locks in this tutorial as well as in this chapter program ' s reference.

• Problem of test Signal before using the TCP connection

  Right now my application uses a SocketConnection TCP to communicate with a remote server.  It works fine, but I'm trying to make sure that my program can correctly handle the situation to move to an area with no coverage.

  When I run my application, if I uncheck the box "on the cover" for GSM and CDMA under Network properties, my app fine until it calls the OutputStreamWriter.write () function to send something on the socket connection.  I have it in a try/catch block, but it just seems to hang instead of throwing an exception.

  How can I check the signal before attempting to send data on the SocketConnection?

  To facilitate clear life upwards, here's the order of what happens:

  1 application starts on the cover.

  2 SocketConnection made successfully.

  3 OutputStreamWriter successfully SocketConnection.

  4. coverage is lost

  5 OutputStreamWriter.write () is called, but freezes instead of throwing an exception.

  The socket connection output stream write operations do not throw an exception when there is no coverage is the correct behavior. That's because on cellular networks the IP tunnel to the carrier (and therefore the TCP connections on this tunnel) survives loss of coverage. For example, if your application opens a connection TCP from a BlackBerry, then the BlackBerry loses coverage, then take cover, say, 1 minute later, the TCP connection opened by your application will continue works fine, unless intermediate network component or your server closes the connection due to inactivity.

• die remote desktop during the VPN connection

• How to disable the vibrations during the (de-) connection phone?

  Hallo, I am very often in the distance of the phone, when SW3 and phone are connection/disconnection again and again... [It is not a problem, the BT range is given by hw:], but I want to disable notifications of vibrations on smartwatch (one and two vibrations, over and over..)

  It is only your battery life and it is confusing for me if I have some notification or not...

  I don't know that I had no such problem few weeks ago, maybe with a new update, that he was turning. I can't find the settings how to disable this "feature".

  Perhaps it is caused by the "Find my phone" application, but this app is in SW3 by default now, without all the parameters.

  Thanks for any help, have a nice day!

  [LG G3, custom ROM (KK), SW3 LCA43 5.1.1]

  It is not a native function, so it is probably a part of 3:rd application that you have downloaded.

  Cerberus seems to have this feature, for example: http://www.androidwearapps.org/2015/03/cerberus-anti-theft-added-support-for.html and I also saw in some other forums as watchmaker seems to have this feature. I haven't checked all the apps that you have, so it could be several applications that has this.

  It looks like also some custom watch faces have this feature and they do not need to be the face of active standby to give the vibration alert: https://productforums.google.com/forum/#! topic/android-wear/GM9B-ahTStA

  Are you sure you tried to expel all the apps from third 3:rd?

• GANYMEDE + failing during the web connection, succeeding the SSH connection.

  I have a Ganymede server + configured (tac_plus, freeware).  I have one point of access configured to use Ganymede + local as default authentication method.  Name of user and password works fine at the guests of SSH/vty, Console connection.  However, it fails when you try to access the web interface.  When you try to access the ip point http://[access] / he asks a login:

  The server [ap ip] request your username and password.  The server reports that it is Level_15_access.

  If I put in my credentails Ganymede, the authentication prompt appears again.

  If I add ip http authentication aaa - authentication of [name of the authentication list] connection, it allows access.  I was under the impression that I would not need to add this if RADIUS is configured as the default authentication method.

  Current config:

   aaa new-model ! ! aaa authentication login default group tacacs+ local aaa authentication login TACAL group tacacs+ local aaa authorization exec default group tacacs+ local aaa authorization commands 15 default group tacacs+ local aaa accounting commands 15 default start-stop group tacacs+ aaa session-id common

   ip http server ip http authentication aaa login-authentication TACAL ip http secure-server ip http help-path http://www.cisco.com/warp/public/779/smbiz/prodconfig/help/eag !

  It's been a while since I've done AAA on the part of a switch HTTP. However, looking at my notes I used only:

   ip http authentication aaa

  Basically, without specifying the method. Give that a try and let me know if it works. If it does not do a debugging on Ganymede authentications and after the output here.

  Thank you for evaluating useful messages!

• How can I get the brands during the video connection to the video

  Hello

  I don't know what happened with the cs6 first, I need to get my angles (marks) little linking the video to the video which means as the end point of the 1st video early in the second. For example when I drag video to another video, it allows to show me a few brands on the videos which shows they are related between them without losing the video images. I do not see the brands more and I really need them to not cut sequences. Now, since I do not have these angles I Zoom in each time to connect them properly. Help, please!

• international keyboard not recognized during the first connection (later Yes)

  I am running Win XP Pro on fusion 3.1.1 on a macbook pro with a french keyboard (AZERTY).

  When I log in time of Win XP first (IE after the start of the windows virtual machine), he believes that my keyboard is the U.S. standard layout (QWERTY). Once windows is started, everything works fine and it recognizes the right keyboard layout, even if I am disconnected from the computer, but if I stop and restart the windows virtual machine, I once again enter my password, as if I had a U.S. keyboard.

  Does anyone know how to define the layout of the keyboard for the VM BEFORE it is fully initialized.

  Hello

  Try this, IIRC, so this was the place to correct.

  Go to: Control Panel > regional and Language Options > Advanced tab > choose your language for non-Unicode programs AND especially:

  Check the box that says: "apply all settings to the current user account and to the default user profile.

  Then click OK

• Why my laptop wireless computer connect to the internet first thing in the morning and late at night, but not during the day.

  I wonder if you can help me please?

  I have problems with my satellite internet access on my laptop wireless.  He beautifully connects to the router and the signal is excellent. However, I'm unable to connect to the internet.  I can use the laptop first thing in the morning because it connects right away, but I would say that 95% of the day I can't use it at all.  Sometimes it will work later in the evening.  I learned this could be due to the intensity of the signal and that some suppliers to fall during the day.  My desk top connects perfectly (if the weather permits it) but is not on the wireless network.  I had no problem with my laptop when I used my previous service provider.  It becomes more frustrating that the inability to use the internet visited my lap top unnecessary.  I can't use it on my neighbors wireless network no problem at all but they we internet different provider.  Can you please help because I don't know why it works first thing in the morning and sometimes late at night, but not during the day?  No matter where the lap top is the first thing in the morning, it will work even if it is forty feet away.  I can sit during the day with my phone right by my router and it still not connect to internet even though the router signal strength is excellent and desktop is on the internet.  Any help would be great, because it leads me into the wall!  I am using WIndows 7 on my lap top from acer.

  Kind regards

  Julie

  I would like to thank everyone for their help with my question.  I can tell you now that I have it solved and I'm pretty embarrassed to say the least.  Following a change of internet service provider, I put a cable into the wrong port on the router... silly me!  It works perfectly now. Thank you once again.

  My MacBook froze during the installation of the update at El Capitan and now I am unable to connect to any except the screen of the guest user. There was a message of panic, and somewhere in there, he said no set of OS. I tried to start without danger, it does not work either.

  This general situation may be similar to what is mentioned in this sequel to thread of the CSA

  and if the remedy is to use instructions; detailed and I hope they are correct...

  Re: Restart fails after installation of El Capitan help!

  Or you can try and see on the repair of the system and then if your disk utility can

  See the Macintosh HD, as a boot volume, you could restart from OS X Recovery to

  the Mac system, to see if this solves the problem. There may be more than one cause.

  You could try and boot into OS X Recovery, utilities out there, and other options are available.

  • OS X: on OS X Recovery - Apple Support

  This example uses a special partition on the hard drive of recovery which is not in the

  same disc that the Mac OS X section; However if your hard drive is missing, these other

  items may also be at risk. You must have and maintain backups of your duplicate content

  on the external storage drives closed; In addition, a Time Machine backup helps to restore.

  • Apple OS X and Time Machine tips:

  http://pondini.org/OSX/home.html

  • Tips for OS X - using HD recovery:

  http://pondini.org/OSX/RecoveryHD.html

  {Using the utility disc and other tools can be done from the boot OS X Recovery volume

  Beware of the fact these tools can also delete or reformat your content; wiping.}

  Don't know what to say; you could see visiting an Apple store with genius if

  There is an official store. Usually for best time planning you would contact them for an appointment.

  • Make an appointment at an Apple Retail Store Genius Bar
  • Find an Apple authorized service provider
  • https://locate.Apple.com/country - Apple - find places - selector of country (if outside the U.S.)

  Or if there is no official retail Apple Store with genius, the following suggestion would be to contact

  a service provider authorized Apple, an independent specialist who is qualified in the repair of Apple.

  In any case...

  Good luck & happy computing!

• Satellite A110-378 loses the WLan connection during downloads of big

  Hi all
  I have a Toshiba Satellite A110-378 series and a wireless network problem. The card is an Intel 3945abg. I can connect with the router ADSL (USR9106) with WPA security is enabled. I can navigate on the Internet, but for a large download (or shall file a copy) the connection stop responding. Windows still displays the connection, but after a few minutes I got an error message.

  To re - establish it, I need to 'fix' the connection. The driver is the latest in Intel, and I tried to disable the power settings. Seems that the problem is the same with my ethernet card (I'm the check).

  Any ideas?
  Thank you very much.
  Alessandro

  Hi Alex

  In my opinion, there is always possibility of losing the motivations and download WLAN connectivity more I prefer the LAN connection (sometimes runs during the night). Check this with connection to the local network, but perhaps is another side responsible for the interruption of the download.

• No internet connection AFTER startup, but only works during the boot.

  Hi all

  Have a Win XP MCE (Media Center Edition) Dell laptop running.  I can only connect to internet when the system is even start, and I click on the shortcut to IE or Firefox. Once the system completes the startup it connects me to the internet WITHOUT problem & with good signal and good connection speeds.  System connect wirelessly through a Linksys router.

  If I left the initialization of the system ended up - and I'm trying to connect to IE or Firefox - the hourglass appears for a minute and then disappears and I get no connection!

  This means that I must always start the internet connection while system is always initialize, and if I end the connection I get only back to restart system in place and opening connection when appear the icons on the desktop for IE or Firefox!

  I am puzzled by this and have no idea what to do to solve the problem!
  TNX a lot!

  Hello

  • What were the changes made before the issue occur?

  Verify that if the problem exists in Mode safe mode with networking, if the computer works as expected in mode safe mode with networking, and then we can solve the problem in the clean boot state.
  a. refer to the article below for the procedure safe mode in Windows XP
  A description of the options to start in Windows XP Mode
  http://support.Microsoft.com/kb/315222

  b. it is a possibility that there is a startup program that is launched with a command line and it appears.
