COM-Ports "richtig" enumerieren

Beitrag von pickelrobert »

Hallo,

bislang habe ich die COM-Ports in einer Schleife versucht zu öffnen, und wenn dies gelang, in eine Liste der "verfügbaren" Ports eingetragen.

Dummerweise fallen so bereits verwendete Ports ungewollt mit heraus, obwohl diese physikalisch existieren.

Wie gehe ich das Problem "korrekt" an?

Danke schon mal.

Ich mache das über die Registry, das funktioniert getestet von Windows 2000 bis Windows 10.
Ansonst gibt es noch den komplizierteren Weg über die setupapi.dll, da habe ich aber keinen Code bzw. nur für HID-Geräte.

Code: Alles auswählen

Procedure SearchAndShowSerialPorts()

Hier habe ich noch einen Testcode von mir für die SetupAPI.dll gefunden.

Peter

Die Ausgabe ist z.B.:

Code: Alles auswählen

Re: COM-Ports "richtig" enumerieren

Beitrag von Kiffi »

Es gibt den Kommandozeile-Befehl "mode", der die verfügbaren COM-Ports auflistet.
Mit ein wenig Text-Parsing könnte man sich was aus dem Output zusammenfriemeln:

Code: Alles auswählen

Compiler = RunProgram("cmd.exe", "/c mode", "", #PB_Program_Open | #PB_Program_Read | #PB_Program_Hide)
Output = ""
If Compiler
  While ProgramRunning(Compiler)
    If AvailableProgramOutput(Compiler)
      Output + ReadProgramString(Compiler) + Chr(13)
    EndIf
  Wend
  CloseProgram(Compiler)
EndIf
MessageRequester("Output", Output)
Und hier noch eine Lösung, die die ComPorts mittels vbs/wmi ermittelt:

Re: COM-Ports "richtig" enumerieren

Hallo Kiffi,

die Version mit 'mode' gibt keine geöffneten Ports aus. Und die VBS/WMI-Version zeigt mir keine USB-Seriell-Adapter an, nur die vorhandenen vom Mainboard.
