You will have to manually setup any relevant event handlers and properties again for the TComport component.

Well you may need to manually edit the dfm file and pas file in notepad or some other text editor. Delete the reference to TComport the the form declaration in the pas file. Then try and open the dfm file and delete the TComport section from the DFM file. I think the DFM file is highly likely to be in a binary format though so you will have to use the convert.exe which is in the bin folder of your version of Delphi to convert it to text before you edit it.

My guess would be to make a backup of the .pas file and .dfm, select ignore on all those errors. Once loaded delete the comport component from the form (if it still exists). Then add backthe TComPort component. This will make the component have all the default values for the latest version of the component
