LOW Level ASCII Sequences using a DLL

The DLL disk is included with every RF Terminal system. To install the

program, run the INSTALL.EXE program from Windows Explorer. The program, PromptCOM comes in both 16 bit and 32 bit versions of a

Windows Dynamic Link Library (DLL) that allows programmers to easily add the ability to send prompts and receive data from their RF Terminal via the RF Base Station or direct serial link.

The Application Programming Interface (API) for PromptCOM consists of the following functions:

InitComDLL Initializes the PromptCOM system

CloseComDLL Shuts down the promptCOM system and frees resources without closing the parent application.

Setup Setup is used to configure the COM port

SendCommand This function both sends a command to the terminal with the given ID

GetCommData This function returns the data entered at the remote unit for that prompt

DataAvailable Use this function to check if there is data to process

before calling GetCommData

There are sample programs distributed on the diskette for Visual Basic, Access and Delphi. There is also a Visual Basic code example that does not require the DLL. Use the Help System as documentation and view the README file for the latest changes.

PromptCOM/ActiveX

Drop-in components are tools that are added to your programming environment "tool kit". There are a variety of different technologies around for implementing a drop-in component such as VBX (for Visual Basic) and VCL (for Delphi and C Builder) and COM (ActiveX). Only the ActiveX variety are widely compatible with almost all development environments.

PromptCOM/ActiveX is a drop in COM component that allow programmers to easily add the ability to send prompts to and receive data from their R/F Terminal via an RF Base Station. It is compatible with
