Serial I/O (RS232) Using Delphi (RS232)

This page demonstrates how to perform Serial I/O via RS232 using Delphi). Last Modified 09-30-03, links fixed 10-24-09 All Intel PCs have one or two serial ports usually referred to as Com1 and Com2. Thousands of components, code samples, tools and useful content for developers are available here for you. Most of components are updated regularly so you can find here their latest version for using within Delphi 10.3 Rio as well. For the information, about 10-20 products are actualised every week. Rezharts Delphi code will never work cause a lack of understanding serial communication. I will not repeat all the steps necessary to make things running but he should try out the command processor component (ComDataPacket) in addition to the comport component.

All Intel PCs have one or two serial ports usually referred to as Com1 and Com2. These comm ports provide voltages and pin outs consistent with RS-232C. Normally, these ports are used for mice, modems, printers, and the like.

Under DOS, it was possible to directly access these ports. However, Windows 95 and above forbid direct hardware access. Therefore, this page exists to help get around windows. /ca-drivers-license-lookup.html.

  • Winsoft ComPort 6.0 for Delphi XE10.1-XE10.3 Rio Cracked Delphi and C Builder component for serial communication for Windows. Communication with devices connected to serial port easy of use and very powerful uses multithreading and overlapping for maximum performance available for Delphi/C.
  • This is Just an update on this Delphi issue. I managed to make a working example (it works pretty good) on Delphi 7 using ComPort VLC component to control a series of LEDs thru Serial COMM Software example with source code, Arduino code and ComPort VLC, all available on my site to download.

Erik Salaj from Winsoft has a com port component for Delphi XE6 Firemonkey on OSX available. This is the latest com port component in a series of com port components that he has available for Windows, Android, and IOS. The implementation is pretty basic with the demo application that comes with the component reading data using a timer. There is a 3rd party component for this: Comport for Android. See also Broadcast Receivers in Delphi XE5 Android for information about Bluetooth serial communication. As I understand, it would require some work to get this implemented, since the needed api's are not fully translated to Delphi yet. – LU RD Dec 14 '13 at 8:31.

Generic References

I provide numerous references in Serial I/O (RS232).

Basic Commands

I really don't get it, with all the available windows API commands, why doesn't Delphi provide a built-in wrapper function for SerialIO?

Borland provides the following Delphi FAQ's (delphi-faq.zip 915K).

  • 16193: Setting comm port configuration programmatically under Win95
  • 16199: Changing com port config via Win95 CommConfig Dialog
    (Pure gold :) .. except that only the baud rate can be changed :( the other 4 fields are ignored.
  • 16400: How can I dial out through the modem under Win32?
    How to write to the comm port
  • 16774: How can I determine the names of the installed comm ports?
    The data is read from the registry
In addition to the Delphi File I/O commands, there are several Windows API commands. Most of these comm commands (such as CommConfigDialog) are defined in kernel32. Speakers

Writing a Port

Delphi Serial Port Component

The following code from FAQ 16400 shows how to write to the comm port as a file. The code in the FAQ also verifies a valid handle before writing to it. Warning: There is an error in the FAQ - NumberWritten must be dword not LongInt

This code works for comports 1 thru 9, but not for ports 10 and higher. Instead, use code similar to the following

Reading a Port

Well, reading the port is almost trivial .. if you know the trick.

You must configure the TimeOutBuffer. I don't know what good values should be, so I used 300.

Having done that, ReadFile waits until I scan a barcode. Eventually, I will use ReadFileEx because it will call a routine when a barcode is scanned.

Once the port is open and configured, here are 2 routines that will read the port. For test purposes, each was connected to its own button. Uh, both routines work when run from the IDE .. the second refuses to work if you double click on the exe file. I have no idea why.

This next routine works from the IDE, but not if you run the app by double clicking the exe file.

When CreateFile, ReadFile, and WriteFile are used, Delphi does not use MSComm. Instead, it uses the following Kernel32 commands (found using Depends.exe)

If you try to search the Delphi 5 help for ReadFile, there are no hits. This is because ReadFile is a Windows API command .. not a Delphi command. Instead, click on it in your code and press F1.

Here is a reference that helped me develop this section.

TCommPort

On the Internet, there are several TCommPort type components (see the references below or just search for them).

I have been successful using TCommPort by Dirk Claessens (freeware with full source code).

I strongly suggest using someone else's component rather than trying to build one yourself. Why? Because they have already been tested on numerous systems and various undocumented 'features' have been taken into account.

Converting Delphi 2007 Indy 10.2.3 to Delphi 2009 Indy 10.5.5 [Edit]
Hello, I am currently attempting to port over a Delphi 2007 project that uses Indy 10.2.3 (very successfully) to Delphi 2009 and Indy 10.5.5 (I just got the latest development build this morning). I think I am running into an encoding issue, but am not sure. Specifically, IDHTTP with SSL calls an old CGI and the CGI returns a .zip file and I then save it to the disk. In 2007 and before this worked perfectly. In 2009, it is not. Here is the examples of the 2 different results (though cut way short in the post) I am getting back: 2007: 'PK'#3#4#$14#0#0#0#8#0'rLQ9žrPb€'#0..

DesignIDE package and porting Delphi 7 components to Delphi XE2
HI I am porting components from Delphi7 to Delphi XE2, and started run in problems regarding MaskProp.dcu, some of the components uses this, and is looking for TMaskProperty class. After a lot of browsing on the net i figured out that all these units is packaged in the designide.dcp. So i have the design time component in a package that requires the designide.dcp and then the runtime component package that reguires the designtime package for the component. In the runtime component package i get errors regarding the MaskProp.dcu and the TMaskProperty class. I dont know what to do from ..
dll fails when compiled with delphi 2010, but works with delphi 7
I may be doing good if someone can just point me to the right forum I have not created a dll for some time and have not written one with 2010 before. The dll I am creating will be called as a cfx function by either a ColdFusion or BlueDragon webserver. I have written cfx DLLs in the past. The function declaration is below, it is the standard declaration from ColdFusion or Bluegradon documention on creating a CFX. procedure ProcessTagRequest(Request: TCFXRequest); export; cdecl; Since this was the first time using 2010 I wrote a very basic function to build off that was not much mor..
Delphi 2006
Hello I have a Delphi 2006 project that when I set a breakpoint, and then compile and run (F9) the program from the IDE the program no longer 'breaks' at the breakpoint, irrespective of where the breakpoint was set. The problem does not exists with any other projects, and I have made not changes to the Projects 'Options' since the problem has started. Any suggestions as to the cause of the problem and/or a solution. TIA John On Thu, 29 Jan 2009 06:15:52 +0200, John Eastman wrote: > Hello > > I have a Delphi 2006 project that when I set a breakp..
Delphi 3 breakpoints no longer working
Yes, I know that Delphi 3 is a dinosaur, but I still have code and components that require D3. Today I launched D3, and was puzzled as to why all of the breakpoints that I set were being ignored. I checked the Environment options, and yes, I had Integrated Debugging checked on. But try as I may, no project that I open, or create, will recognize a breakpoint. For instance, I can set a breakpoint on the button1.caption line, and when the code is run from within the IDE, the code execution does not pause on the breakpoint. procedure TForm1.Button1Click(Sender: TObject); begin butto..
Trying to call a .DLL from Delphi XE (used to work with Delphi 6 :-) )
Hi everyone, I have a problem where perhaps some one could help point me in the right direction. In Delphi 6 I used a stand alone package to train a neural netowrk,. The trained neural network was stored as a .DEF file. The standalone software provided a .DLL and Delphi code to call the network and get the prediced values from your sw. (The .DLL was created in 2002 and apparently is 32 bit.) I have'nt used it for years but am now coming back to it.. I now use Delphi XE on Windows 7 (32 bit) The old .exe's I had compiled from that time work fine. However in Delphi XE ..

Import Component search does not work in Delphi 2009
In the Delphi 2009 IDE from menu selections ComponentImport Component the Import Component form is displayed. If I select Import Type Library to display the type library list and then use the search function, it does not work. Similarly, from menu selections ViewRegistered Type Libraries, the search filter does not work. Interestingly the Camtasia Studio 5 video dealing with the new COM components and ridl file showed the search function which is really a filter working fine. Does anyone else have this problem? If not, does anyone have a solution short of reinstalling my developme..
