Communication port is not working properly


COM1 and COM2 refer to a computer's communications, or serial, ports. COM1 ports are often used on older PCs to connect network devices, digital cameras and mice. Faulty drivers software that enables the hardware to communicate with the operating system or incorrect hardware configuration can influence COM1 behavior. In rare cases, the expansion card that adds the serial ports to the PC can fail, rendering both COM1 and COM2 ports useless. To repair a COM1 port, you must determine what is preventing the port from working before attempting a solution.

Click "Start." Go to "Control Panel" and then click "Hardware & Sound." Select "Device Manager" from the submenu. Expand "Ports (COM & LPT)." Double-click "COM1." Review Device Status on the General tab to check for problems with the software driver. If the message "The Device Is Working Properly" appears, click "OK" to close the window; otherwise, look up the error message on Microsoft Support. Follow the directions in the Knowledge Base to correct the issue. Press "Alt" and "V" to open View. Scroll to "Resources by Type." Press "Enter." Double-click "Interrupt Request (IRQ)" to see a list of devices. Double-click "Communications Port (COM1)." Check the term to the left of COM1 to see if the card uses an ISA or PCI interface. If the card uses a PCI interface, it can use the same IRQ as another PCI device without producing a hardware conflict. If the device is ISA, it needs its own IRQ. Go to the "Resources" tab. If "No Conflicts" appears in the Conflicting Device List, close the window; otherwise, uncheck "Use Automatic Settings." Click the drop-down menu and select each configuration until the port no longer interferes with another device. If conflicts occur with each configuration, double-click "IRQ"; you may need to try different configurations before Windows gives you permission to edit the interrupt request. Click the up or down arrow to change the IRQ until the message "No Devices Are Conflicting" appears in the Conflict Information field. Click "OK" to close each window. Click "Yes" when prompted. Connect a device to the COM1 port to test the port. If the device doesn't respond, shut down the computer and then unplug the power cable. Disconnect all devices from the back of the PC. Remove the case cover and touch the computer's chassis. Set the computer on its side so that the PCI and ISA cards sit at a 90-degree angle to the floor. Find the serial ports on the back of the PC. Look on the opposite side of the case to find the associated card. Shine a flashlight onto the card and make sure that the copper contacts are not visible. If you can see the contacts, reseat the card in its slot so that it's fully installed to the motherboard. Reassemble the case and boot into Windows to test the COM1 port. If the port still fails to work, you may need to replace the serial port card.

Cant use my usb



Refresh and reinstall USB Ports Of Your Computer Hello there, the other day i tried refreshing and reinstalling the USB ports on my PC, as some of my connecting devices are not recognized. I present the detailed procedure on refreshing the USB ports.
Let’s go!!

Here are the steps to refresh/reinstall/uninstalling the USB ports on the computer.

The USB port needs to be refreshed to make sure that no other device has captured the USB port of the computer. The Mouse, video camera, your external USB hard disk; what ever it may be.

Follow the steps given below to refresh USB ports.

1. Right-click My Computer icon on the desktop, and then select Properties.
2. Click the Hardware tab.
3. Click the Device Manager Button.
4. Click the plus (+) sign to the left of Universal Serial Bus controllers.
5. Right-click the device listed under Universal Serial Bus controller and select Uninstall.
6. Click OK to confirm the removal of the device.

Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.

7. Shut down the computer.

CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.

8. Wait for 5 seconds and then restart the computer. When the computer restarts, a "Windows has detected new or added hardware" message window will open.

The above steps will refresh the USB ports.

Now connect the USB devices like mouse, video camera, your external USB hard disk...USB hubs...whatever you like and the drivers should install automatically.

Tip: It is always recommended to connect the main USB devices at the rear end USB port. As they require more power to initiate.


The above steps are for XP operating system. When coming to the matter of Vista, please note the changes below:
===========================
1) Right-click Computer icon from the desktop , and then click Properties to open the System Properties window, and then select the Device Manager tab.

2) Click the Plus (+) sign next to Universal Serial Bus Controllers/Root hub.

3) Click the USB Composite Device entry to highlight it, and then click Remove. If a screen appears to confirm the deletion, confirm the deletion.

4) Disconnect the USB cable to the all-in-one, wait a couple seconds, and then reconnect the cable. This should restart Windows device detection (Plug and Play).

5) A New Hardware found screen may appear, click next through all of the screens that appear for the Wizard to install the USB Composite Device. Click Finish once the wizard completes.


If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Not able to connect to BT Homehub wireless Toshiba Satellite Pro


  1. Click the Start button getcontent.aspx?assetid=4f6cbd09-148c-4dd8-b1f2-48f232a2fd33&documentset=en-us&renderkey=signed1, click Control Panel, and then double-click Bluetooth Devices.
  2. Click the device that you want to change, and then click Properties.
  3. Do any of the following:
    • To change the name of the device, click the General tab, type a new name, and then click OK.
    • To enable a service, click the Services tab, select the check box next to the service, and then click OK.
    • To disable a service, click the Services tab, clear the check box next to the service, and then click OK.
    • To make your computer discoverable to Bluetooth enabled devices, in the Bluetooth Devices dialog box, click the Options tab, and then select the Allow Bluetooth devices to find this computer check box.
    • To make Bluetooth enabled devices discoverable to your computer, in the Bluetooth Devices dialog box, click the Options tab, and then select the Allow Bluetooth devices to connect to this computer check box.
    • To be notified when a Bluetooth enabled device wants to connect to your computer, in the Bluetooth Devices dialog box, click the Options tab, and then select the Alert me when a new Bluetooth device wants to connect check box.
    Warning
    • To help protect your computer, only make your computer discoverable when you want a Bluetooth enabled device to find your computer.

Some computer programs require a COM port (also called a serial port) to communicate with a Bluetooth enabled device. For example:
  • A program that synchronizes contacts with a mobile phone
  • A program that extracts Global Positioning System (GPS) coordinates from a GPS receiver
When you use the Add Bluetooth Device Wizard to add a Bluetooth enabled device to your computer, you create an incoming COM port, which permits your device to connect to a program on your computer, and an outgoing COM port, which permits a program on your computer to connect to your device. Usually, you only need to use one of these COM ports.
To decide which COM port to use, you can check the information that came with the program or your Bluetooth enabled device, or go to the manufacturer’s website.
If you're still not sure which COM port to use, try each COM port, one at a time, and use the one that successfully allows the program and your device to communicate.

What do "ports" mean when adding printer?


An interface on a computer to which you can connect a device. Personal computers have various types of ports. Internally, there are several ports for connecting disk drives, display screens, and keyboards. Externally, personal computers have ports for connecting modems, printers, mice, and other peripheral devices.

Almost all personal computers come with a serial RS-232C port or RS-422 port for connecting a modem or mouse and a parallel port for connecting a printer.
On PCs, the parallel port is a Centronics interface that uses a 25-pin connector. SCSI (Small Computer System Interface) ports support higher transmission speeds than do conventional ports and enable you to attach up to seven devices to the same port.

In TCP/IP and UDP networks, an endpoint to a logical connection. The port number identifies what type of port it is. For example, port 80 is used for HTTP traffic.

Also see Well-Known TCP Port Numbers in the Quick Reference section of Webopedia.
