Com PortComponent
The Async Professional port component builds the foundation forall communications applications. The simplest application might contain asingle TApdComPort; a more complex application might contain one or more portcomponents and many other components that rely on the services of a TApdComPort(terminal windows, modems, and so on).
The TApdComPort component, which contains properties andmethods for the following:
Configuring the serial port hardware and Windowscommunications driver (buffer sizes, line parameters, flow control).
Providing information about the state of the serial port(modem signals, line errors).
Transmitting and receiving data.
Interfacing with the TApdDataPacket component to identifyand handle received data. Sketchup pro 2017 license code.

If you need to support network or Internet communications usingWinsock, you should consider using theTApdWinsockPort instead of the TApdComPort. Since the TApdWinsockPort is adescendant of the TApdComPort, it retains all capabilities of the TApdComPort,and adds support for Winsock.

serial com port monitor, good component for Delphi 2009? [Edit]
I have been looking for a good component that compiles with Delphi 2009 and supports serial com port analyzing ('sniffing'). To give an example, the hhd Serial Port Monitor Control is the functionality we are looking for, but it doesn't work well with Delphi (many errors). It should not interfere or lock the COM port and should work even if the COM port is already in use. (Lot of components we tried needed a lock on the COM port). Wasp (software) is reading barcodes over the COM port and we need to capture the COM data and then display a dialogbox to give the end-user a choic..
how to read data from serial port or usb port
hi,all i know powerbuilder is powerful in database development. i just want to know if i can get data from serial port or usb, and how? thanx I have read data from the serial port by using the Microsoft plugin MSCOMM32.OCX that is included in several of Microsoft's products, but specifically it is included with VISUAL STUDIO. Once you install it in your machine, you can use it from PB by declaring an OLE object container. You then can call its methods and use its properties.

Code Porting
Hi people, Basically, I am moving an app from Delphi 5 to Delphi 2009 which is all great (yeah right!) and I am having a couple of issues with some thirdparty components that we have the source code for. Being that I wanted to make the task as easy as possible, I was able to download the component in Delphi 2007 format. I have now managed to port that to 2009 so it compiles only with warnings and no errors. So all is good at this moment. Now I am trying to install the component into the IDE by using the install menu option from the project manager. This is where I run into errors. ..

Virtual Serial Port Driver emulates COM-ports
Virtual Serial Ports Driver XP creates two pure virtual serial ports in your system which are virtually connected to each other. For other Windows applications, virtual ports will be seen exactly as two real serial ports connected via null-modem cable. With virtual ports created by Virtual Serial Port Driver XP you can connect applications to each other and exchange data between them without occupying your real serial ports and using hardware wiring. Virtual link between virtual serial ports is much faster then real null-modem cable connection and depends on your processor speed. The latest ..
