• Com and Lpt ports not in Device Manager

  I have not "Ports" option appears in Device Manager in Windows 7.  I have an internal modem and I am trying to attach my blackberry, and there is no port - Com or Lpt.  It's just not there.  Any ideas?

  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".

  BIOS WARNING: Change to the BIOS/complementary metal oxide semiconductor (CMOS) settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  3. If the steps above does not resolve, then you will need to install the driver manually.

• Impression on the LPT ports on Server 2008

  Hi all

  I use an application via RDP on a Server 2008 R2 server. The application prints directly to a pre-defined LPT port, on the same server, which is redirected. When I print it does not say that it cannot find the port.

  I tried running the application directly on the server and print also fails.

  I have the same setup and configuration running on Server 2003 without problem. It also fails on windows7?

  If someone could give me some advice of where to start the search it would be highly appreciated.

  Thank you very much

• Running 3 monitors, 2 card Radeon 5450 and 1 port of the motherboard

  I have a p7-1154 HP which has two DVI ports on the motherboard, but I needed to run a third monitor so I installed a HP 5450 PCI Radeon card that has a DVI, HDMI and VGA port, but I can use only 2 of them at the time - or DVI, VGA or HDMI, and VGA. Motherboard ports don't work at all now, so I'm in the same place that I was before I even bought the video card. I was under the impression that I would be able to use existing DVI ports on the motherboard as well as DVI/HDMI and VGA video card port together... How can I get there?

  Thank you very mucho.

  Daniel

  My friend, welcome to the forum.

  Here is the Product Specifications page for the computer.  If you look at the section titled "Integrated graphics", you will notice that it says the following: * integrated video is not available if a graphics card is installed.  Therefore, there is no way to use a third-party monitor.

• Tecra A8 and Adv Port Replicator III - no audio output from the port replicator

  I have a Tecra A8 anchored on an Advanced Port Replicator III. All ports (network, USB, video) with the exception of the AUDIO ports seem to work well. I can get sound from the headphone jack on the front of the A8, but nothing since the station docking ports. Is there a docking station driver or something I need to install to get the sound from the docking station not the laptop?

  Hello

  The Advanced Port Replicator III supports the line and line port left.
  As already suggested by user above; Check if you are using the command-line output port!

• Tecra M3 and Advanced Port Replicator III: not recognized as docking station

  Hello!

  Just install my new M3 and Advanced Port Replicator III. Everything works fine, but the Port Replicator is not recognized as a Docking Station (No disconnect in menu button start XP; pressing disconnect button on the Port Replicator itself has no effect either).

  Is TI WHEREAS behavior?
  Thank you in advance.

  Hello

  You reinstall the unit with the recovery CD?
  As far as I know that the TOSHIBA Mobile Extension3 for Windows XP is responsible for the good condition of the market of the docking station.
  Well, I recommend to reinstall this driver and utility.
  Perhaps the installation of the new driver will solve this problem.

  Good bye

• How can I recover data when the firewire and USB ports do not work?

  My MacBook Pro has been flooded by water, and no ports work. Anyone know how I can get information on the new system or hard drive and my computer?   The cost of repairs to the machine is $ 800, so I'm going to buy a new.

  Remove the hard drive in an external enclosure supporting USB or Firewire. Connect to another computer to retrieve your data. This requires that the player was not damaged.

• How to get AC 97 Front Panel Audio and Microphone ports to work with Windows 8

  I have a m7277c HP Media Center that uses the motherboard Asus P5LP-(Lithium-UL8E) and has an Audio Jack and Microphone AC 97 spec ports on the front panel. I tried to install the Codec AC 97 drivers for Windows 7 and they do not work for Windows 8. The 'High Definition Audio Codec"Windows 8 drivers only work for the Ports on the rear panel, not the Ports on the front panel.

  How can I get AC 97 Front Panel Audio and Microphone ports to work with Windows 8?

  Hello

  Your model has not been tested for the use of Windows 8.

  For this reason, HP cannot provide instructions to upgrade or Windows 8 pilots.

  Therefore, it will be very difficult to provide a solution.

• Porting to ARM LM3S811, PWM and serial port issues

  Read my previous post: http://forums.ni.com/ni/board/message?board.id=420&thread.id=1996

  I have problems again, I
  corrupted data sent through port sΘrie 0 when you use the OR
  pilot series on the LM3S811. I also get code error-1073807339 when reading that
  data inside labview with VISA, sent my arm to my PC.

  I have
  think the timings may be wrong, but I put t know
  where to look for baud rate divisor for
  UART0. S 3, 811 is Xtal 6 Mhz, 8 Mhz not like the 3S 8962.

  I have
  also tested the PWM on the frequency and scope dosen t match if I ask
  for 1 kHz, I'm moving 666 Hz. Seems like affecting the Xtal 6 Mhz in
  uVision is not enough.

  OK, here's the solution.

  Open 'startup.s '.

  Goto line 193:

  ; set the system clock to run at 50 MHz
  ; SysCtlClockSet(SYSCTL_SYSDIV_4 |) SYSCTL_USE_PLL |
  ;                SYSCTL_XTAL_8MHZ | SYSCTL_OSC_MAIN);

  LDR R0 = 0X01C002C0
  BL SysCtlClockSet

  B __main

  Replace R0, with the right values in "sysctl.h" line 236:

  in my case the value of the 6 Mhz Crystal which is "0x000002C0".

  Calendar of PWM is restored and serial port works fine now.

• How can I find my external and internal port number

  I am trying to access the internet via a live ethernet cable from my router, except the computer im trying to use is new to the House, but is under xp. I also have a laptop which I use to ask these questions, which accesses the internet via a wireless connection. I open 'Internet Properties' and entered my IP address and I am now looking for my external and internal port numbers try to connect. Is it and most easy way? I'm on the right track? Help, please. :)

  If you really have a router, then this router should affect your computer all the configuration settings that it needs to connect to the internet (or local) automatically via DHCP.  The "TCP/IP properties" correct settings on your computer must be set to "Obtain an IP address automatically" and "Obtain DNS server address automatically".  If your router is configured correctly, it will automatically load these settings, such as all you need to do is to connect your computer to your router.  If this does not work, then you must download the manual of your router and verify its configuration.

• CQ62-410US stuck with "Several monitor - Clone View" and VGA port does not

  Hello!

  I have a Compaq CQ62-410US computer laptop with an Intel GMA 4500 M (onboard) video card and a port output VGA, Windows 7 x 64 operating system. A few weeks back the screen was broken (kick straight punch of a child) and nothing could be transmitted via the VGA output either, but the laptop booted and I could hear the sound of Windows 7 logon. I never checked before the VGA output port.
  Yesterday, I replaced the screen broke up with and identical. The fine (full-screen) display in case of back work (boot from USB Flash and the sea + test images), but in Windows 7, two vertical black stripes appeared on the sides because lower than the native resolution. The resolution can be changed at native 1366 x 768 "Screen resolution" because the display is set by default to "Multiple monitors" (I have no other monitor connected, only the built-in screen) and "display of Clone. The built-in display is set as secondary and 'Generic non - PnP' is defined as primary. Any attempt to set the integrated display as primary function or to change the mode "display single" / "Extend view" leads to a black screen with the backlight always on, no matter where I change the settings - in the 'screen Resolution' or 'Graphic properties' (from driver Intel). In the 'Screen Resolution' window the pictogram of the screens show a single screen split in two, and when I press the button "Identify" it shows on the screen ' 1 | 2 ", as you left half of the screen is the main display and half right is the secondary display.
  I put a Philips monitor to the VGA port, Windows detects and installs the appropriate driver, but there is no picture any of mode I put - Clone, Extend, unique display - monitor.
  I tested 3 view of the site of Compaq drivers for my device and the GMA 4500 M drivers from Intel, but the problem is the same (with the drivers from the site intel, on I get only black screen with backlighting.) Pilots are unstable, sometimes at the opening session, page is only a black screen (but before the windows loading screen appear very well) that cannot be changed by "Fn + F4" / "F4" (change view) but a black with the backlight is turned off.
  Due to the replacement of the hard disk, I can't use restore of the operating system that is installed at the factory.
  Please advise me how to solve the display problem and enable the port VGA (get the image on the external monitor).
  Thank you in advance.
  SSM there is not output through the VGA input even at the BIOS screen (no material or to issue independent of the operating system support?).

  I have attached a screenshot.

  Update: I started a live Knoppix CD, and I don't find any problem - unique in 1366 x 768 display configuration; I could even play a game in 3D (OpenGL). While hanging from one monitor to the VGA port, it was found, but when trying to print image to it the OS hung. I guess it's a hardware problem, something to do with the video controller.

  

  I thought about it, it's the GPU, I think that some of the contacts are damaged. Today even in the BIOS screen I see in the middle of the screen a vertical thin purple line which was bounded two screens on a single screen, and all now have a purple tint.

  I had a quick glance at the GPU and surprise - it is glued to the motherboard, no sleeve, no welding. The motherboard chipset is also stuck.

  See the attached images.

  Thank you for the excellent support. I will never buy anything with Compaq logo on it.

  In safe mode the PVID is 1 VLAN by default. You can do this by entering the command #switchport trunk vlan native {number of vlan}. If Cisco is configured to accept and send the marked packets and has an IP address in the subnet of VLAN 20, it should be able to communicate with other devices in VLAN 20.
