Remember all telephone main lines are mostly digital however the lines to most US houses are usually analog. However like anything you can understand how it works then it can help when developing code which needs to interface with the device.Īlthough 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. It’s obviously doesn’t take much to install and use a modem however this will depend on the purpose. If you need to utilize serial modem or any other serial communication devices in your Delphi application, you should use this component. it provide interfaces for Delphi programmers to use the serial communication ports. ![]() CPort is a Delphi component created by Dejan Crnila. ![]()
