Module - eASYNC

The module eASYNC consists of one program eASYNC.exe, written in

Visual Basic.

Overview

eASYNC.exe

The eASYNC.exe is the Visual Basic component of the eASYNC module.

The program communicates with two processes: the eKERNEL.exe and

the asynchronous modem attached to a COM port. The eKERNEL.exe is

the central engine that centralizes all database access and communication

with input and output capable modules.

The eASYNC.exe communicates with eKERNEL.exe by means of TCP

sockets. In this communication, eASYNC.exe is a TCP client software that

connects to the other component, acting as TCP server software.

At startup, eASYNC.exe contacts the eKERNEL.exe by means of a socket

connection. Startup parameters are required to identify eASYNC.exe,

and locate the eKERNEL.exe program. These parameters are set in the

Properties section of the shortcut that initiates eASYNC.exe. This shortcut

is usually located in the Windows Startup group (click

Start, and choose

Programs > Startup).

Figure 47

Typical parameters in the shortcut

In the example in Figure 47 "Typical parameters in the shortcut" (page

293), the eASYNC.exe identifies itself as belonging to Site 1, and specifies

the location of eKERNEL through IP address *LOCAL and port 3105.

The special value *LOCAL refers to the assigned IP address of the first

NIC adapter found in the PC. You can find this use the IPCONFIG.exe
