This tutorial is a little rough around the edges, but it is far enough along that I thought youd want whats here. Despite its sins, it has been tested. Port Forward Serial Number' title='Port Forward Serial Number' />April 2. Windows XP and Delphi 4, and everything was fine down to. Write. String is, of course capable of sending more. It is probably fine past there, too. I revisited the program in the course of working with serial comms with the marvelous Arduino microprocessor. There are a number of articles about serial comms with Arduinos at my Arduino How To site. Level 4 section, but I make no promises The best is probably the Delphi tutorial about bi directional serial comms. That is built upon the work done in the tutorial you are currently reading. Unless you have some expertise, you might want to finish this one before attempting the more advanced tutorial. Things you can learn here will make it easier for you to understand it. Maybe you, like me, wanted to hook a microprocessor up to your big computer, for instance an Arduino While I was doing the April 2. I created a zip file you can download with the sourcecode and even the compiled. It shows you how to send messages from one PC to another via the serial port. It does not require anything more than Delphi 2 and Win. I think it will work with higher versions of Delphi and Windows. For a different approach to accessing not only the COM ports, but other ports too, see my tutorial about the free DLL Inp. These portpowered RS232 to 422485 converters change TD and RD RS232 lines to 422485 signals. All of our serial port converters feature Automatic Send Data Control.

Port Forward Serial Number' title='Port Forward Serial Number' />Out. For more about using the serial port, see my serial port tutorial. I also offer a page about using a COM port to communicate between microprocessors and Windows PCs. Although it is couched in Arduino terms, much of the information is applicable to other contexts. Dont forget There are inexpensive USB devices which provide a Windows PC with a virtual COM port. Sadly, the USB to parallel port printer devices seem less well suited to connecting things other than printers. At the moment, this tutorial tells you about sending data only one way, from PC A, to PC B. For bi directional serial communications, you have to work harder. I would suggest that you finish the page you are reading first, as everything here is part of the bidirectional answer. I have done a further tutorial on how to accomplish bi directional serial comms with Windows, when you are ready for it. This will not give you an all singing, all dancing applicationWhat it will do, I hope, is give you a starting point, useful in its own limited way, and perhaps also useful if you want to go further. Along the way, the tutorial illustrates the general skill of using Windows API calls directly, instead of with the help of Delphi wrappers. The latter is preferable. Before you try to do anything yourself with the serial port, make sure that your hardware is working properly. I make many references to Hyperterminal in what follows. That used to come with Windows, but doesnt now, and isnt always installed on older machines. You can use any simple serial terminal software. Ive been using Pu. TTY, but havent used it much yet. It is free, and runs on Windows an Linux. For what were doing here, you only need to download putty. Connect two PCs with a null modem cable. Start Hyperterminal on each of them. Win 9. 8 It is in ProgramsAccessoriesCommunications. It is one of the free things which come with Windows, but it isnt always installed. To install Settings Control Panel AddRemove Programs, The Windows Setup tab. Once your computers have Hyperterminal, start it up. Your start menu will probably have been given a link to the Hyperterminal folder. Port-Forwarding-Wizard_1.png' alt='Port Forward Serial Number' title='Port Forward Serial Number' />You need to double click on Hypertrm. The entries with. When you first start Hyperterminal, youll probably get the New Connection Wizard. If you want your machines to be consistent with what I say in this tutorial, create a connection called DD5. HTC Delphi Demo 5. Hyper. Terminal Connection. It doesnt matter what you put in the phone number fields. Just Connect Using. Com ports. Of course it has to be the right Com port. Oh goodie. the fun has started already. I really hate serial comms. A detour On one of my machines, a laptop, the port has a little sticker I put on it saying it is Com. Hyperterminal didnt offer a Com. Com. 1 gave rise to Could not open. File Properties is what you need to try again. The Configure button worked for Com. Next I right clicked My Computer, clicked Properties, went into Device Manager, Infra Red Devices. I said Disable in this profile. Rebooted. At last I COULD talk from one computer to the other over the null modem, using Com. Bah. I then went to the second machine, started Hyperterminal, started a new connection. Called it DD5. 5HTC, too. No need for different names. Thence to the Configure dialog for each machines Com port. Most of the settings dont matter much in this application. Try. Bits per second 9. Flow Hardware or none. One more thing to do. Call Call via the menus, or just click on the Call button a little telephone. You should see Connnected in the status bar, windows lower left. Now, all being well it is quite possible that it wont be, when you type on one of the computers, what you typed will appear on the other. And vice versa. Without local echo, you wont see what you type on the machine you are on. Get that much working Good luck. Serial comms. Did I say that. If you want, you can turn on a local echo. File Properties Settings. When you leave Hyperterminal, you are asked Do you want to save session Saying yes preserves any settings you may have made.
