Using ActiveXperts Serial Port Component with Delphi. ActiveXperts Serial Port Component is a software development kit (SDK) that enables the user to communicate to a device over a serial interface. May 10, 2011 - is a freeware tool we've used with great success for many years. PLC Serial Communication help. 2005-06-02 04:36:41 PM. I'm looking to communicate with a PLC via a serial link.

Specifically the hex decimal side of things.
CPort is a Delphi component created by Dejan Crnila. It provide interfaces for Delphi programmers to use the serial communication ports. If you need to utilize serial modem or any other serial communication devices in your Delphi application, you should use this component.It’s obviously doesn’t take much to install and use a modem however this will depend on the purpose. However like anything you can understand how it works then it can help when developing code which needs to interface with the device.Although a modem is often just thought of as a method for connecting to the internet, there is much more to the device and it’s applications, A modem actually converts digital to analog and the opposite way to. Remember all telephone main lines are mostly digital however the lines to most US houses are usually analog. This means that it they are designed to transmit, a voltage wave which is an exact replica of the sound wave coming from human speech.
This voltage wave is called an analog wave.The serial post or UART serial port as it’s correctly known is an input/output device. Why is this important? Well because the modem has a serial port communicating between them and the computer, your code will need to traverse this connection in order to make it work.Dealing with serial devices is in some ways m,ore complicated than standard network programming.
Being able to send commands however to such a device vastly increases the potential of your code to facilitate communication between different devices. So for example it can be especially useful in the modern world of relaying proxy servers and IP addresses through different devices. Adobe photoshop cs2 9.0.2 no-activation repack sfx bsbt apps pc. Take for instance the use of a who needs to use normal home IP addresses to create a pool of IP addresses.The AT-CMD Tester and many Delphi applications that need an access to the serial ports use this component as the interface to it. One of them is the miniSMS – a program to read SMS on a cellphone message inbox via PC serial port.It’s a little bit complex for me when I use this component for the first time since I don’t know much about serial communication programming.
