Using QWinsock

In order to send and receive packets of information, computers on the Internet use an established network protocol called TCP/IP (or Transmission Control Protocol/Internet Protocol). When you run a Windows application such as Quarterdeck Mosaic, the application relies upon a Windows driver to open and maintain a "socket" (or connection) to a remote computer. This socket driver, usually called WINSOCK.DLL, allows your computer to communicate with other systems using TCP/IP.
Most often, a WINSOCK.DLL driver is installed into your \WINDOWS or \WINDOWS\SYSTEM directory. When a Winsock-using application makes a network request, WINSOCK.DLL is loaded into memory (if it has not already been loaded). 
To load Winsock, Windows first searches in these two Windows directories for a WINSOCK.DLL. If none is found, all of the directories included in the PATH statement of the AUTOEXEC.BAT file are searched. Because it takes extra time to look in these additional directories  particularly if your PATH statement is quite long  the quickest (and, thus, recommended) method is to place WINSOCK.DLL with your other Windows files where Windows can easily find it.
If, during installation, you elect to install QWinsock as your sole Winsock, our WINSOCK.DLL will be installed into your Windows directory. When you load a 16-bit Winsock application, QWinsock is loaded automatically.

All Winsock applications that run under Windows 3.1 are 16-bit. Programs which are written specifically for Windows 95 (and which do not run under Windows 3.1) are 32-bit. If you load a 32-bit Winsock application in Windows 95, it will find and use your 32-bit Winsock driver. If a 32-bit version of Winsock is not found, the application will refuse to run.
The Quarterdeck Winsock Control Window
When Quarterdeck's WINSOCK.DLL driver loads into memory, the Quarterdeck Winsock control window appears in the corner of your screen. By clicking in the upper-left corner of the window, you can access many QWinsock features.

In addition to connecting to and disconnecting from your Provider, you can view or change QWinsock settings, run Quarterdeck Ping (a network diagnostic tool), or make changes to your Location and Connection profiles through Location Manager, the configuration component of QWinsock. Extensive online help is also available from the control menu. All menu items can be accessed with the mouse or via the keyboard.
QWinsock also includes a toolbar from which you can perform the same tasks with a single mouse click. The buttons, from left to right, are: Connect, Disconnect, Settings, Ping, Location Manager, and Help.
If a toolbar button is grayed out, that option is not currently available. (For instance, the Disconnect button is only available when you are online; the Connect button is available when you are offline.)
Using QWinsock with an Existing Winsock
If you want the ability to switch between two Winsocks, simply copy the non-Quarterdeck WINSOCK.DLL driver into your \WINDOWS or \WINDOWS\SYSTEM directory and leave QWinsock's WINSOCK.DLL in the directory where all of your other QWinsock files are installed. 
When you want to use a non-Quarterdeck Winsock with your network card or modem:
 u 	Start any Winsock application. 
This causes the WINSOCK.DLL in your \WINDOWS or \WINDOWS\SYSTEM directory to be loaded into memory. 
To use Quarterdeck Winsock with your modem and dial-up Internet account:
1	Close out any Winsock applications that are running. (This unloads the current Winsock driver from memory.)
2	Double-click the QWinsock icon in your Quarterdeck program group to load QWinsock into memory.
3	Run any Winsock-using applications you wish to use.
4	When you are finished using QWinsock, close all of your Winsock applications, then close QWinsock by selecting Close from its control menu. 

If you have enabled the Keep Winsock in Memory feature in your QWinsock Settings, QWinsock remains in memory even if you close all Winsock applications. To switch between Winsock drivers, you must either disable this feature before closing your Winsock applications, manually close QWinsock, or restart Windows.
When installed as a secondary Winsock, Quarterdeck Winsock in no way alters your current networking setup. QWinsock does not interfere with your ability to access the Internet through your direct network connection. (While you can continue to use your network connection after installing QWinsock, you can only use one Winsock driver at a time. You can alternate between QWinsock and another Winsock, but not use them simultaneously.)
If you decide, after alternating Winsock drivers for a while, that you want to use QWinsock as your sole WINSOCK.DLL:
1	Make a backup copy of the non-Quarterdeck Winsock driver that currently exists in your Windows directory.
2	Copy the WINSOCK.DLL from your QWinsock directory to your \WINDOWS directory.
