ExamplesĬomExample.dpr - shows some basic send-recieve features Note: Do not save packages under Delphi IDE. You might not get this error until the next time you try to start Delphi. If it complains that it can't install it because it can't find a library, you probably did not put the run-time package in the search path. ComPort components appear in 'CPortLib' page of component pallete. Click 'Compile' button in Package window to compile the package and 'Install' button to register ComPort into the IDE. Use File/Open menu item to open design-time package source file (see above). Now you have to install design-time package. Now move run-time package library file or files (see above) from ComPort folder to a folder that is accessible through the search PATH (e.g. Click 'Compile' button in Package window to compile the library.

Use 'File/Open' menu item in Delphi IDE to open ComPort run-time package source file (see above). That helps make sure CPort gets installed dual-mode. I recommend installing CPort while running Delphi 2006 in the 'all personalities' mode of Delphi, rather than in the Delphi only personality. Use the instructions below for all other Delphi versions. Add to the Library Path the new ComPort folder (Tools-Environment Options-Library-Library Path). Create a new folder under Delphi directory and extract sources zip file into new folder. Remove all previously installed files of ComPort Library (TComPort component).

The master branch is focused on Delphi and all CBuilder support has been removed. This library is a fork of the original ComPort Library 4.10, which can found here: Īs it is a fork, some of the original commit messages are still accessible. While nowadays COM ports get less important for communication in favor for USB access, it is still in use as virtual ports, especially as simple communication protocol for maker boards. Originally, the COM port was the name of the serial port interface of IBM-PC compatible computers.

The ComPort Library contains code to access COM Ports. When USB COM port disconnected error occures, handler OnAfterClose is executed and exception 'Port Disconnected' (TComException = CE_PortDisconnected) is generated.

Solution isn't perfect and still is possible to suspend application on infinite WaitForSingleObject, especially in the case of very slow transmission speeds (300-600 bauds), but it's a lot better than before. ComPort library with USB COM port disconnected issue fixed.
