What are the modem of the light?
The modem lights are simply lights that occur on external modems. Depending on whether the lights are dark, activated and stable or flashing, each modem will provide an activity indication that is currently taking place between the modem and the computer's attached hard disk. The current state of the lights helps the end user to know whether the connection is established if the connection is active or whether the connection has dropped for some reason.
The activity of the light modem is usually referred to as handshaking . Basically, when the model is used, the device interacts with the computer. The modem receives input from the computer and again provides the hard drive the influx of data. Both devices confirm the receipt of the received data and orders issued to others. In this sense, Handshake, unlike a gesture between two individuals who agreed to exchange or action plan.
This interaction or Handshake, which is marked with a modem of light, is made possible by the presence of universal asynchronousImage/transmitters located on the hard disk of the computer. Microchip Uart is what actually allows the computer to talk to the modem and process the data received from the modem. It is not possible to create a relationship with an external modem without UART.
On a standard external modem, several modem types are found. AA or automatic response light means that the modem is connected and ready to accept an incoming call. The light of the CD or carrier detector acknowledges that the computer and modem have achieved connection and communication here and there. HS or high -speed light will be illuminated if the modem is ready to transfer data at a relatively fast pace. Finally, MR or modem prepared light, the ND user allows you to know that the modem is set to operate.
6 If the connection between the computer and the modem is broken, it usually takes nothing but the rapid resetting of the modem and using the key, switch or buttons toModem starting the connection recovery process.
