Use Synaser?
One System to rule them all, One Code to find them,
One IDE to bring them all, and to the Framework bind them,
in the Land of Redmond, where the Windows lie

Hello,
No I should use tcomport

Why TComport ?
TLazserial is based on TComport and synaser and it has a method to detect the serial ports ( see port settings in the  sertest demo project of Tlazserial)

There is a procedure into the CPort.pas doing exactly that:
Code: Pascal  [Select][+][-]
  1. procedure EnumComPorts(Ports: TStrings);

In case you work only under Windows an opportunity could be to use the windows registry, as in the thread here:
