Industrial plants comprise many devices interconnected in different ways: simple data collection units without any built-in intelligence, more intelligent devices such as sensors with built-in intelligence, single-loop controllers or programmable controllers and supervisory systems. Bluetooth wireless technology is potentially useful for all of these.

Realterm is a terminal program specially designed for capturing, controlling and debugging binary and other difficult data streams. It is far better for debugging comms than Hyperterminal. It has no support for dialing modems, BBS etc - that is what hyperterminal does.

Usefull and small terminal emulation program for the Serial port communication. It's working with seven com ports, you can use Transmit Macros. This program is free - download it.

Power Over Ethernet (PoE) also called Power Over Lan (PoL), is one of existing possibilities how to transport data and supply voltage to Ethernet device by already existing net of cabling CAT5 for computer networks (10 Mbit/s and 100 Mbit/s).This standard, which will probably define the future development of Ethernet devices, was finished and authorized in last year’s June as a standard IEEE802.3af.

ISDN is replacing our old analog phones and offers a lot of new services. It is the easy way how to transmit voice and data simultaneously at the same time using an andvantages of a digital communication. Now I want to explain you, how does it really work.

PS2 connector is in these day present almost in every computer. It is used to connect keyboard or mouse (or some else pointing device). This article contains information about connection, communication (host-to-device and device-to-host) over ps2 port and also about coding of keyboard

Asymmetric digital subscriber line (ADSL) uses existing twisted pair telephone lines to create access paths for high-speed data communications and transmits at speeds up to 8.1Mbps to a subscriber. This article explains the basic function of ADSL transceivers and their modulation scheme.

Why you should use the Java for Embedded Systems? Java is a modern object-oriented programming language. Java allows for direct implementation of the analysis and design models. Here is a few Java devlopment tools for Embedded systems.

A full-featured simulator for serious analog designers. Sophisticated, internal models allow you to simulate everything from high-frequency systems to low-power IC designs. Draw on the expansive library of models to create off-the-shelf parts, or create models for new devices. Fully explore the relationships in your design with "what if" scenarios before committing to final implementation.

This document provides an introduction to intelligent modems, the AT command set and the concepts behind many of the commands. The AT commands are used to configure the modem to your preferred operating mode and to instruct the modem to do what you want it to do.
