This is a follow up. In response to Chris Rake's answer: ports open fine, there is one good read, and then just zero length strings in ports buffers.

The old server works fine. This problem occurs on our new server only. We want to run the same app on the new server. Of course not at the same time. So we shut down the old server before starting the new one. But we still get just one good read from the serial devices. We do not get any error message. Would it be possible to get a phone number so that we could call the NI and describe our environment and the issue we came across in more detail. Thanks.

    Hello Wontsey & Welcome
    On 6-4-06 I installed Norton Internet Security 3.0.1 for Mac. I thought maybe my problem was related to the firewall part so I unistalled it and turned the Apple firewall that came with the computer back on.
    This did not help. In fact, when I try to open “Help” from the desktop menu the program opens and then immediately closes so I can’t access it.
    I hate to have to tell you this Norton is the problem, looking into uninstalling it, the uninstallers that came with it are not effective so no matter you do not have the CD/DVD go to their site to get the Uninstaller
    UseCocktail or OnyXto find the invisable files. Just follow Macjacks directive.
    This is covered in this Topic thread,abandoning Norton Internet Security see the files Macjack speaks of in the topic thread. If you have questions post in the same forum a new topic this thread is archive, click on the link and then click"back to topic list". This is why i first came to Apple discussions, to get help with the mess Norton can make on Panther and found help as you will. It is not a Safari issue per say, rather a Norton problem.
    Best of luck.

    when i try to FaceTime on my iPod touch, and the call gets accepted it says connecting... and then just goes to FaceTime failed. this started after a 800 number called my FaceTime. i have tried putting in several other emails & on diff wifi. suggestions??
    i have also tried facetiming with several other people. the same thing has hapened every single time and it has always worked just fine until that 800 number called me.

    Judging by all the posts on the forum, there seems to be an issue at Apple's end, although they have made no announcement on their status page. Some users have reported that Apple is aware of the issue.

    Trying to select the Calendar check box in iCloud window and then it asks me If I want to merge I hit ok and the it tries to ad see spinning fan icon and then just quits and is then unchecked.  Does Anyone have a solution to fix this?  It works just fine on all other 5 Macs I have.  I have tried to sign out and in and even restart the computer.  I am running Yosemite on all 6 of my Macs.

  • TS1362 I have downloaded the song "Bruises" by Band of Skulls and it plays to about 1.20 remaining and then just stops and goes to the next song. How do you fix this?

    I have downloaded the song "Bruises" by Band of Skulls and it plays to about 1.20 remaining and then just stops and goes to the next song. How do you fix this?

    I removed the song from the itunes library and then added it again, but the same issue still exists.
    I'd report the problem to the iTunes Store, then.
    Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
    Find the item that is not playing properly. If you can't see "Report a Problem" next to the item, click the "Report a problem" button. Now click the "Report a Problem" link next to the item.

  • Apps won't install/update on my iPhone 4S (ios 6.01) says installing and then just stops!? Is there any fix for this?

    Okay so basically this morning (20th November 2012) I turned on my iPhone and went onto the App Store to check for app updates which I do every morning, and there was an update for the Wikipedia app and another app, however... When I tried to update these apps, the password conformation box came up as usual and then the message saying the app was installing popped up. But this message disappeared instantly and nothing happened. When I try to download apps from the App Store, the exact same problem keeps happening. Sometimes after two or three tries an app will install but only occasionally. I have tried rebooting my iPhone but with no luck. I have over 11gb of memory left on my iPhone and my Internet connection is strong enough so I'm completely confused! Does anyone know a possible reason for this or maybe even a working fix... Also knowing someone else has this problem would be nice :)
    Look forward to some responses :)

  • When I select Apple TV and the mirroring option it holds for 5 to 10 seconds and then just goes back to iPhone. Was working fine this morning

    Sorry - more information. Using it off iPhone 4S

    Hello Theo,
    I have a few recommendations for you. First if you havent already, restart the iPhone following iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting http://support.apple.com/kb/ht1430.
    Restarting your device
    Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
    Press and hold the Sleep/Wake button until the Apple logo appears.
    I would also unplug power to your Apple TV and modem/router, wait a good 30 seconds, and plug it all back up.
    If none of that gets it going again, then have a look at this article for troubleshooting Airplay:
    Troubleshooting AirPlay and AirPlay Mirroring

    Cheers,

  • My entire iCloud mail system is messed up. I have worked on this for days. It works sometimes after I restart my computer and then just stops for no reason. In addition when the mail stops it refuses to let me reboot my iMac. Any ideas?

    I'm praying somebody here has an idea to help me. iCloud has suddenly gone nuts on my iMac. It works only when it wants to work and then stops for no reason. When it stops I am no longer able to click the mail icon and open any mail even the old stuff that was there. No changes were made to my computer. This all started out of the blue. When the mail stops working it will not close out to allow me to restart my computer. It won't even allow a forced quit. No changes were made to my machine. My iPhone still get mail but only after I click the mail icon. It does not pull mail in and show how many new emails I have like it did before. I have a me.com email if that helps. Any ideas would be truly appreciated.

    This is the second macbook pro i have owned in the past two weeks.  I am ready to return it for good if this is a chronic issue. Please help if you have had this same issue.

  • HT2101 my i phne was exposed to a little water and then i put it under a table lamp to ensure ebvaporation of water . During this the phone was switched off. Later when i turned the phone n , it worked pine for 5 min and then the temp alarm came. Need hel

    Hi my iphone showed signs of moisture in camera area and so i kept it under a table lamp for a few hrs after switching off the phone. Later the moisture was gone so i switched on the phone and after 5 min of perfect operation an High temp alarm came. Every time i switch off the phone works fro 5 min and ten gets the alarm. How can i get my phone back to normal?

    Thanks for the reply, just being positive as the phone turns on fine and every thing works ok for 5 min and then the temperature alarm comes on. I am hoping that the issue may be limited to a perticular temperature sensor etc.
    I have got the phone opened and there was little water signs that have been cleaned with alcohol but the issue remains the same. I believe that the temp alarm is caused due to the phone being kept under the table lamp which raised the phones temp beyond the acceptable range and hence may be damaged one of the temp sensors. Heard that there are around 5 different temp sensors in the iphone. If any one has more knowledge please advise on how i can get this fixed.Thanks.

  • This iPod cannot be used because the required software is not installed. Run the iTunes installer to remove iTunes and then reinstall it again

    I tried yesterday to install iTunes on a XP Services Pack 3 Pc, It said that it couldn't install it. So after much reading last night, i downloaded Revo Uninstaller Pro, and uninstalled all apple software, included Bonjour, Quicktime and Apple Support along with iTunes. I then, used Ccleaner to double check that nothing apple related was left in the registry.
    After doing all the above, i rebooted the PC, and downloaded a fresh copy of iTunes from the website, and installed it. I installed the first time of asking. I then pulged in my Son's new iPod, and it detected it as a scanner/Camera, and behind that was a message that said the following:" This iPod cannot be used because the required software is not installed. Run the iTunes installer to remove iTunes then install iTunes again"
    I've tried doing this, and it keeps coming up with the same message
    Can anyone help please

    In Windows 7, go to Control Panel (usually in the Start menu) and look for Add and Remove Programs. It will load a long list of programs. Find iTunes on that list and uninstall it. Then try using the 64-bit installer.

  • After I open FireFax 4 to my home page and then try to navigate elsewhere, I do not have access to the back arrow to return to the home page. What setting is causing this to happen?

    Toshiba Satellite Laptop
    Vista Home Premium
    Firefox 4.0 recently installed
    Every time I load Firefox, my home page comes up.
    After going to another page, I do not see the back arrow highlighted, and the only way to get to the home page, I have to click on the Home button in the upper right part of the screen and get a new tab. Annoying - yes. Practical - no. I even uninstalled 4 and reloaded with the same results each time.

    Then you need a clean install.
    First export your bookmarks to a html file. (Bookmarks/Unsorted bookmarks will bring you History page where you can export your bookmarks). Note down your add-ons too.
    Uninstall the old FF using free software like Revo Uninstaller. This will delete all the root directories and registries of old FF.
    Now download the latest version of FF and install it. You can re-import your bookmarks from your saved html file.
    You may still have to do the fix in my first post.
    Post here whether this worked for you.

  • I have an iPhone4 and whenever I try to buy songs off of iTunes they will not finish downloading. It will say that there is a download error and then that it can't be downloaded at this time. It will get to about 3MG of how ever much needs to be downloade

    I've tried this many times and never seems to work

    Thank you for the reply. I am on a home network. ISP is centurylink DSL service located in midwest, so USA. WPA security type with 10 digit numerical password. I verified IMAP does work on my network, my gmail account adds perfectly fine in mail on the mac. I also checked that there is not a proxy server setup. *this has been occuring in all 3 of the places I have lived in the past 5 years or so, no matter the ISP.
    What is really bizarre is my iphone 4s works fine with everything. Notes sync with icloud. Mail syncs with my icloud and gmail accounts fine. The iphone is also connecting to the same wireless network. Another thing, my iphone works with a hotmail account too, which is POP (dang microsoft), but I wonder why apple won't let it work on mail on the macs.

  • When I click on Firefox in recent days, there's a long delay and then I'm told to click on the simplified sign-on. How can I fix this?

    Firefox always used to take me to my homepage - AOL. Now it doesn't unless I click on the simplified back-up access method.
    == This happened ==
    Every time Firefox opened
    == several days ago

    If you can't install on top of the current installation then you need to delete or rename the current Firefox program folder to do a clean install.
    It is possible that your security software is using or locking files, so you can try to temporarily disable that software during the installation.
