I tray to changing 3 new keyboards but still reads the problem. What's your problem?


OK what type of keyboard are you using Serial or USB? A serial type keyboard has a round end that plugs into the computer's PURPLE port (the Green Port is for the mouse).

A USB type keyboard has a flat end that plugs into one of the computer's usb ports.

If you are using a Serial (Round end) type keyboard, it is not Plug and Play (meaning you cannot unplug it or plug it in while the computer is running or it will not be recognized). You can only plug or unplug the serial keyboard when the computer is off. If you turn the computer off and plug it in good then reboot and you still have a problem then since you have tried 3 different keyboards, maybe the Purple Serial Port where the keyboard plugs into the computer is bad. Try a USB Type Keyboard.

A USB (Flat end) keyboard is Plug and Play. You can unplug and plug it while the computer is on. Also you have the luxury of plugging it into any one of the computer's usb ports.

I don't know how enable infrared port in my pc - ibm thinkpad x 41


By default, currently available ThinkPads come with the external serial port disabled and Infrared enabled on COM1. To use the serial port on COM1 you must either disable infrared or change infrared so that it uses alternate resources. If you are not using infrared for printing or file sharing it is recommended that it be disabled. Here are the steps to follow to enable infrared :

1. Double-click your ThinkPad Features or ThinkPad Configuration icon located in the ThinkPad folder on your desktop.

2. Locate the Infrared button located on the left-hand side of this configuration screen and click it once. (Note: If you hold your mouse pointer over any of the icons in this configuration screen the button will be identified at the bottom in the status window.)

3. Change Infrared from "Disable" to "Enable" and click "OK".
4. Locate the serial port icon and click it once.
5. Select serial port "enable" and insure that the COM PORT setting is "COM 1" and click "OK".
6. Shut down and restart the computer.

Both printer and 9 pin serial ports not working


What has changed? One solution is to go into BIOS when you first turn on your PC hit <del> key. Make sure the ports are enabled. The second solution is to make sure you didn't add a device with serial ports or something which is sharing the same IRQs, which is 3 4 and 7 traditionally (for COM1/2 and parallel port).

If you tried all this and it doesnt work, then somehow the chip on the motherboard which handles these (the UART chip) has broke, you need to replace the motherboard or buy a card with serial and parallel ports on it (this should be quite cheap, ie 10-20 dollars).

Computer says no contact with machine have tried everything


Youn don't say what Windows flavor you're using, or whether you have a serial port or not. I'm going to guess you have a laptop with Vista on it, and the laptop has no serial port for you to connect the 7570's cable.
You need to get either a serial to USB cable that works with the 7570 (read some of the posts in this section. There's at least two or three that do), or another device called a Port Replicator, that has the serial port as well as a parallel port for printing, and perhaps one or two USB ports.
In my case, I have two of the latter ones, the Targus PA090U and the PA075U, and both need no drivers with Vista and work OK. They simply get recognized when you plug them into a USB port and are available to you, except that in my case, the serial port always defaults to COM port 4.
The other reason why you may not be getting a connection may be found in your Machine Configuration, in PCD_WIN. In version 2.0, which is the one I have, go to the Machine menu option, and at the bottom, click on Configuration.
Here make sure the COM port is the correct number, and then set the speed to LOW. That works for me.
Good luck!

for com port you have to assign keyboard and you will need drivers cos not recognised as plug and play
