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

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
