Module - eESPA

The module eESPA consists of one program. The program is eESPA.exe

and is written in Visual Basic (v6.0).

In general, the programs reside in the default directory C:\SOPHO

Messenger@Net\Exe, unless otherwise implemented in your environment.

Note: In release 4.0 an additional implementation is available that you

can activate by specifying manufacturer ESPA and model VSK. In most

cases, the new VSK implementation is likely to be more compatible than

the *BASE system and therefore the preferred method to configure

the eESPA module.

Manufacturer ESPA and model BASE

For backwards compatibility, to activate the original implementation of

module eESPA by specifying manufacturer ESPA and model *BASE.

Overview

eESPA.exe

The eESPA.exe is a Visual Basic component of the eESPA module.

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

external paging equipment. The eKERNEL.exe is the central engine that

centralizes all database access and communication with input and output

capable modules.

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

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

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

At start up, eESPA.exe contacts the eKERNEL.exe by means of a socket

connection. eESPA.exe requires at start up a few parameters, so that

eESPA can identify itself and locate the eKERNEL.exe program. This

is carried out by means of parameters in the properties section of the

shortcut that initiates eESPA.exe. This shortcut is usually located in the

Windows Startup group.
