[Update 05

Einige Geräte benötigen eine COM-Port-ID, die in einem bestimmten Bereich liegt, beispielsweise zwischen COM1 und COM4. Möglicherweise hat Windows dem Port, den Sie ändern müssen, eine andere ID zugewiesen. Dies ist eine relativ einfache Prozedur So weisen Sie einem USB-Gerät unter Windows 10 einen COM-Anschluss zu Mache eine Datei, in die Du die Steuerzeichen als Hex reinschreibst. Oeffne den COM Port mit den korrekten Einstellungen mit einem Terminal Programm und gehe in die Shell wobei der Port dabei offen gelassen wird. Dann z.B. copy test.dat COM1 bzw. wahlweise mit / // Use this code to write directly to the COM1 serial port // First, you want to set the mode of the port. You need to set // it only once; it will remain the same until you reboot Die meisten MS-DOS-Anwendungen unterstützen nur die seriellen Anschlüsse COM1 bis COM4. Der Befehl Port ändern ordnet einen seriellen Anschluss einer anderen Portnummer zu, sodass apps, die High-nummerierte com-Anschlüsse nicht unterstützen, auf den seriellen Anschluss zugreifen können. Die Neuzuordnung funktioniert nur für die aktuelle Sitzung und wird nicht beibehalten, wenn Sie sich von einer Sitzung abmelden und dann wieder anmelden

For reading some information from COM port you can try next command: type COM{n} For sending info to COM port use next command: echo some text > COM{n Most MS-DOS applications support only COM1 through COM4 serial ports. The change port command maps a serial port to a different port number, allowing apps that don't support high-numbered COM ports to access the serial port. Remapping works only for the current session and is not retained if you log off from a session and then log on again mode com1: [baud=b] [parity=p] [data=d] [stop=s] [retry=r] Since windows catches his prinjob and handles it to the printer he should. leave this parameters untouched. Or if he wants to, change them in windows. if nessesary. the line I suggested. was simply rerouting his printer from lpt2 to com1

Und zwar würde ich gerne mit CMD die RS232 Schnittstelle abhören um mich zu vergewissern, dass der Partikelzähler auch mit meinem Prüfstand Programm kommuniziert. Wie könnte ich das verwirklichen denn ich habe bis jetzt nichts im Internet gefunden. Ich Danke euch schonmal im Voraus Anyhow what rest is my Serial port COM1 who probably not working properly. Goggled searching for simple method to test it, but all what I found didn't help me. I have Null Modem cable, Hyper terminal installed,so please if you could suggest some simple program or whatsoever I can use to test and repair Serial Port COM1 specially because USB Serial port device works very slowly. Thanks for any. The new device manager in windows 10 is not showing the com port numbers. Such as COM1 COM2 and so on. If I open the serial bus controller line in device manager it does not provide the port information. What I am trying do is connect to my network switch with a terminal emulation program via an Ethernet cable out of the back of the switch. I know it works since I used it on an old win7 computer. But that computer is long gone. 9600, 8, none, 1. COM1, COM2, or whichever port I. Der installierte Dienst kann über die _service_start.cmd und _service_stop.cmd gestartet und gestoppt werden. Die Port-Einstellungen in der ComPortMan.INI können geändert werden, ohne dass der Dienst neu gestartet wird - die INI wird jedes Mal auf Änderungen geprüft, wenn ein COM-Port neu im System erscheint.

Wie Sie Ihre IP-Adresse mithilfe des Routers herausfinden, erfahren Sie in. Each time when you connect a new COM device or a USB device (true for modems, smartphones, Bluetooth, serial-to-USB converters, etc.), Windows detects it using Plug-n-Play and assigns it some COM port number in the range of 1 to 255. If this device is connected again, the reserved port is assigned to it

In order to test whether the problem in your serial network is fixed, you can reproduce the communication between a COM port and a serial app or device. Serial Port Monitor will help you resend the exact same data to the required COM port so that you can review the reaction of your serial software or device. All you need to do is: 1. Start or open a monitoring session Warum? Während ich ein Programm schreibe, dass auf einen COM-Port zugreift, kann es sein das bei einem Test das Programm halt öfters mal zwischen drin hängen bleibt. Dann wird das Programm nicht ordnungsgemäß beendet und kann deshalb auch den COM-Port nicht schließen. Der Port ist offen. Starte ich das Programm wieder, oder ein anderes Terminal Programm etc., dann kommt die Meldung, dass der COM-Port bereits benutzt wird und daher nicht verfügbar ist. Das ist allerdings. Hallo, Ich möchte einen Hex Befehl AA 11 FF 01 00 12 mit einer batch Datei an einen Com Port senden, an welchem ein Fernseher angeschlossen ist For example, a piece of software may work well with COM1 to 9 but fail if there are no free COM ports below COM10. Another issue may appear when some specific devices take too many ports. For example, some adapters may reserve up to 30 or even more COM ports. In such scenario you are forced to delete COM ports in use in Windows or reassign a used COM port to a different device. In this article. Client COM port mapping allows devices attached to the COM ports on the user's endpoint to be used during virtual sessions. These mappings can be used like any other network mappings. For each COM port, a driver in the OS assigns a symbolic link name such as COM1, COM2, etc, which is then utilized by the applications to access the port
