Amquest VIVA ISA Modems Driver
It is designed to provide a basic understanding of modem types, their operation, and what you need to know for upgrading and where to find upgrading information. As 56K-type modems are the most common modems seen in the marketplace, the modems in widest use, and the modems Amquest VIVA ISA Modems which we see the most problems, the focus of the document is on them.
However, much of what is found here is applicable to other Amquest VIVA ISA Modems Of A Modem The design of a modem can be broken into six functional components: Line Codec: Transforms the analog signal, an oscillating electrical wave varying continuously in frequency, phase and amplitude, into a digital signal, a discrete set of 0's and 1's.
And vice versa.

Responsible for the processing of the digitized waveform. The Data Pump performs error checking and correction, and flow control, and carries out the modem protocol e. Responsible for managing the sync to async communications between the data pump sync and the COM port async. Bus Interface: The electrical throughway for the digital signal to travel from the modem to the rest of the computer.
Modem Driver: The software interface between the modem and the modem Amquest VIVA ISA Modems features of the operating system, features which applications invoke when they want to use the modem. Amquest VIVA ISA Modems
List of Modems - Wiki
The computer code used by the data pump which has the rules implementing the modem protocol in use e. Firmware is used only in modems having a data pump. Characterizing A Modem Modems can be characterized in a number of ways. Location - Where's the modem?
Internal or External. Internal modems will be cycled on and off with the cycling of power to the machine.
Index by number
An external modem sits outside the computer. An external modem connects to the computer via a serial cable from it to an external COM port on the computer. Speed - What is the maximum speed of the modem?
Each number represents the maximum transmission rate of a modem under optimal conditions the 56Kbps figure is inaccurate: Bus Interface - How does modem communicate with the computer? Data Pump - Does the modem Amquest VIVA ISA Modems a data pump? A modem having a data pump will have a chip on it which handles the digital signal processing.
A modem without a data pump on it has the signal processing performed via a virtual device driver. Every external modem has a data pump; only internal modems may not have a data pump.
List of Modems
Modems without a data pump will also not have a controller. As HSP modems are relatively new, it is likely that they will implement some 56K protocol usu.
Controller - Does the modem have a controller? A modem having a controller will have a chip on it which handles the sync to async communication between the data pump sync and Amquest VIVA ISA Modems COM port async.
With an external modem, the COM port is on the outside of the computer and connects to the modem using a serial cable. With an internal modem, the COM port is located on the modem card itself.
Controllerless modems do not have such a controller chip; instead, control functions are implemented through a virtual device driver.
