CPort Component (Serial port interface component for Delphi)

Posted by Daniel - 20,702 Views

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.

The AT-CMD Tester and many of my 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. But when I get used to it, I can see that It’s a good one.

Installing CPort Delphi Component

1. Remove all previously installed files of ComPort Library (TComPort component).
2. Extract Sources zip file into Delphi Lib folder.
3. Use “File/Open” menu item in Delphi IDE to open ComPort run-time package source file (Delphi6: CPortLib6.dpk; Delphi7: CPortLib7.dpk). Click “Compile” button in Package window to compile the library.
4. Now you have to install design-time package. Use File/Open menu item to open design-time package source file (Delphi6: DsgnCPort6.dpk; Delphi7: DsgnCPort7.dpk). Click “Compile” button in Package window to compile the package.
5. Click “Install” button to register ComPort into the IDE. ComPort components appear in “CPortLib” page of component pallete.
