Serial Port Delphi Component
The TComPort component was originally written by Dejan Crnila, it was modified a bit by other people, including me, among others. It didn't need much tweaking, other than a bug fix here and there, and support for new Delphi versions as it came along. The latest version 4.11b is available on here. Like a lot of developers who need to do serial communication, I started using Turbo Power's very capable AsyncPro product, which is still alive, and doing well.

Once you have done that, there's also my tutorial on a program which reads from and writes to a device using the serial port. There's more about these in the. You might find the following of interest: To use the serial port, you can install one or more third party components into your Delphi. I have to admit: This is only the. ComPort, Delphi and C++ Builder component for serial communication on Windows 95/98 and Windows NT/2000. Enables communications with modems or other devices connected to serial port. Uses multithreading and overlapping for maximum performance.
I have said some negative things in the past about AsyncPro, because the complexity in it mixed poorly with the complexity in my products, and when I had to debug things, I found it really hard to debug AsyncPro. Tubular Bells Wav Free Download. But I should introduce a policy here on Delphi Code Monkey; I intend to publically do penance for stupid things I have said in the past. AsyncPro is a fabulous component set, and nothing negative I have said in the past should be held as more correct than the simple fact that lots of people use, and still use AsyncPro, and are happy with it.
Nevertheless, as a person who believes strongly in the 'smaller is beautifuller' concept, almost to an absurd degree, and who has found that the less code I put in my application, the less my application breaks in horrible ways, I still prefer TComPort for the cases where I need to do serial communication in a delphi app. TComPort seems like exactly what I needed for my purposes. So what were my purposes?
I wrote applications that did the following things: 1. Talk to industrial or scientific or laboratory equipment, over an RS-232 or RS-485 link. Some of this equipment including Programmable Logic Controllers, using a common protocol called 'Modbus RTU', or simple Ascii (text based) serial protocols, some with, and some without checksums.
For modbus capable PLCs, I wrote a descendant component that does Modbus client communications, for Delphi, that can talk to a wide range of industrial and process control, and scientific equipment that implements this protocol. Talk over a direct cable link, or a modem link, to equipment at a remote site. Le Seigneur Des Anneaux Le Retour Du Roi Pc Iso Games more. This is incredibly powerful. One application I wrote in the mid 1990s had dialup remote control of an emergency power grid that could be remotely activated by the power utility company in a major midwestern US city, whenever the grid needed additional capacity. Here are things that I didn't need TComPort to do, things that would make AsyncPro a better choice than TComPort: 3. I did not need a full featured 'video terminal emulator' that did fifteen different terminal emulations, including a reliable VT-52, or PC ANSI terminal emulation. You might need this, if you had to connect to an old computer system that provided serial terminals.
I didn't need to use the file transfer protocols from the BBS era, that include XModem, and ZModem. Back in the DOS and BBS days, long before the Internet, those of us who used to 'go online' used to do so using DOS programs called 'Terminal programs', and plastic boxes called 'modems', that let your plain old phone line talk at incredibly high speeds, between 300 and a few thousand bits per second. Just about everything that you could do in Telix, you can do in AsyncPro. AsyncPro (formerly from TurboPower, now open source) is better than TComPort, if you need a full featured video terminal emulator, or x/y/zmodem file transfers. If you still wanted to write a Telix for Windows in Delphi, Async Pro would be perfect for you. So having given AsyncPro its due, let me proceed to why I like TComPort: A.
