Ports are sometimes 'COM' and sometimes 'ASRL.

I have a piece of code that search Active COM ports, tests for a connection, then uses this port.  The problem that I am running is that I am using this code on several laptops with Windows7 and for some reason any, that some laptops list ports COM1, COM3, etc, while others list people like ASRL1, ASRL3, ASRL5, etc.

I did not yet understand why some use different nomenclature, but it throws out of my COM port program  I don't want the operators having to use a menu drop-down and select the port that this test must be entirely automated.

Any ideas on how to solve this problem?

Com references are aliases. Asrl references are canonical names. You can filter the resources to find visa to return either. I got what you use for your list?

    If you have disabled the USB ports in the BIOS (Basic Input Output System), you will need to use a PS2 Keyboard and enter the BIOS for their re help.

  • USB ports are interchangeable?

    I have 8 Ports USB connected to my computer and 3 USB Ports are used by a printer, Scanner and Webcam. I'm sure all three devices are Plug 'n' play.

    The devices work well but that they still work if they have been placed in a different USB port and a new device (e.g. headphones) can be placed in one of the USB Ports 8 or are each USB port ' device-specific?

    Thank you.

    S1

    They will work very well.  Some of your USB ports are more Rapids and those that should be used for devices that can use the speed, if necessary.  What happens is when you switch from one port to the other that a driver for this device is installed on this port.

  • Coordinates GPS are sometimes not accurate

    Hello

    I made a Java application a while back who gets a GPS coordinate every 15 minutes since the Blackberry and sends it to a webserver to display on a map.

    My request (map on the web server and a native app on Blackberry) works very well.  However, from time to time, I get a GPS coordinate which is far away (sometimes even in the middle of the Atlantic ocean).

    It seems very random.

    I've seen this problem on many different models (to name a few): Curve 8330, Curve 8530, Storm 9530, and even the Torch 9800.

    It is very annoying! And not very professional (such as users laughing when the point is in the water).

    I saw this post, which reports a similar problem:

    http://supportforums.BlackBerry.com/T5/Java-development/GPS-location-data-is-sometimes-not-accurate/...

    I tried the suggestion of turning 'Location helping' to 'Off ':

    http://docs.BlackBerry.com/en/smartphone_users/deliverables/3045/Turn_off_location_aiding_400936_11...

    It seems to help a bit, but the problem still sometimes.  It is particularly terrible with a Curve 8530 (in the Mississauga area) where I get weird GPS coordinates every day (in the middle of the ocean or in the North).

    I wanted to do an audit of the points in my code when the card to receive, but it is not an easy task. I compare the new point to the last... and check the distance (in km) between these two points and to reject the last of them if the distance between the two is impossible.  I did that... but I ran into problems when, for example, the Blackberry has been down (or cover, or gps unavailable or dead battery) for several hours (I was then rejecting good GPS coordinates).

    Is there something I could do to avoid this problem?

    Someone has encountered this before?

    Thanks for your help!

    I do actually all of this processing on the device: it is useless to send data to throw!

    I encourage you to take the readings with less or 4 satellites.  And as mentioned, if you have 6 satellites or more, then I would be very very sure that the value is OK and would even not worth checking with the previous.

    If you are only concerned about the values with 5 satellites.  According to my experience on the BlackBerry, they are sometimes good and sometimes not.  Distance and height appear to be good checks, when times are close enough.  When they are not, then I would actually say you should wait until you get a value with 6 satellite offices before you start recording.  If you missed 10 hours, lack even a minute won't be disturbing.

    That said, your validity check server-side seems similar to mine.

    Note that if you use a location, my experience it creates actually a place and then updates, so you should clone the location you get, otherwise he will geet was updated the next value that is passed to you.  You probably already have spotted that.

    Hi emstaples,

    1. check if the device is hidden device.

    i. click on view under view hidden devices

    II. develop all winks in Device Manager

    III. there would be multiple entries in the device in gray Manager uninstall all entries shaded under all the winks and then restart the computer and connect the external device to the computer and check if it works.

    2. check in the BIOS (embedded devices) if the com ports are enabled and set to "auto".

    Hi Johanna,.

    Thanks for posting your query in Microsoft Community.

    I understand that you can not use the USB in Windows 7.

    I imagine the inconvenience that you are experiencing. I will definitely help you with this

    1. you get any error message?

    2 have you tried using different USB ports?

    3. any other USB key works on the computer in question?

    4. do the USB works on any other computer?

    5 have had any changes made to the computer before the show?

    Please follow the methods.

    Method 1:

    Run the Microsoft fixit for the link.

    Hardware devices do not work or are not detected in Windows

    http://support.Microsoft.com/mats/hardware_device_problems/en-us

    Method 2:

    As all devices have same also have USB device associated drivers. Appropriate sometimes drivers not detected after initial installation so reinstalling the drivers can fix the problems.

    You can check after uninstalling and reinstalling USB drivers if you are able to connect. You can disconnect all USB devices and then perform the following steps:

    (a) click Startand then click Control Panel.

    (b) click system and Maintenance, click System, and then click Device Manager.

    (c) Note if the control panel is in Classic view, double-click Systemand then click on Device Manager.

    (d) If you are prompted for an administrator password or a confirmation, type the password, or click allow.

    (e) in Device Manager, double-click to expand the "USB Bus controllers", right click on the controller host, click "Uninstall" and click "OK".
    Check that if at all, there is an exclamation point on the pilot, it suggests problems with the installed driver.

    (f) repeat step 2 to uninstall all items under 'USB Bus controllers'.

    Then, restart your computer and Windows 7 will automatically reinstall all USB controllers.

    We would be more than happy to help you if the steps above did not solve the problem.

  • the white lines (with the key that don't meet pluse) comes and goes randomly

    Hello

    I have iphone 6 more.

    Sometimes vertical Whitelines light 1/random th of screen from the top.

    During this time they display, touchscreen doesn't work sometimes and sometimes it works out gibberish.

    I press somewhere else and something else is pressed.

    Then all of a sudden this problem disappears until I use the phone. (no whitelines or touch that do not meet, everything becomes perfect)

    Once I have it put to sleep or leave for some time the problem will come still sometimes.

    This isn't software issue since I reinstalled 9.2.1 ios again and again with full reset. (deleted all my apps just to be sure)

    There is no hardware failure, because the problem is not persistent and works of my screen and touch all the other times. I think that cables or the connection is loose. given that this problem comes and goes randomly. I can live with that, but its * boring. A sec I talk to someone and I can't cut the call.

    Please help me, Service Center said that I need to replace my phone. They will not understand this and I want to just replace it without reason.

    Tip: I live in India where these people are not able to diagnose even the question and want me to pay for something, I clearly did not cause.

    And since my warranty is out, I have to pay appx ~ $ 470 for a problem that no one can tell me and search the Internet or apply basic logic is simply because cable is at fault.

    Again, there is no hardware or software defect. Its a few wiring loose and noone at the apple repair center wants to diagnose what it is.

    All they want to do is replace the * phone without reason.

    I'm sorry, but the loose wiring is a hardware problem. Since there is no authorized Apple service provider who manage the repairs of the screen, their only alternative is one out of warranty replacement of the device, given that your warranty has expired. To be honest, even here in the United States, if Apple tries to replace the screen and it will not fix the problem, their answer would be the same, a replacement of the officer of the WATCH. They do no wiring at the Genius Bars. Your response is more disabled because of your location. You can see if there is a 3rd party competent repair facility that can run on the device. This decision is yours.

    Try these steps and check if that helps:

    ** Turn it back on. Sometimes a reboot will solve this problem.* *.

    1. close all programs and stop the laptop.

    2. remove all power supplies (battery and power cord)

    3. empty the remaining power by pressing the power on button for 30 seconds (even if you have no power).

    4. put the battery back and start the computer

    5. once fully loaded, right-click on the system tray and select Properties.

    6. This will bring to the top of the "Taskbar and Start Menu Properties" dialog box. The "Notification area" tab.

    7. at the bottom of the tab, is the area 'icons systems. " There is a checkbox for "Power". "check" the box and click on apply or OK.

    Also update your graphics card drivers.

    It works! Tanks a lot Johnny D.81!
