Advanced Usb Port Monitor

[Glauco Schlembach]

Youcan work without any effort with any equipment working over any RS232/RS485/RS422 serial interface. You can use the serial port monitor to monitor data exchange between serial devices connected to a serial port and any Windows application. It may be the measuring device, the industrial controller or amateur radio station, and the other personal computer connected through a z-modem cable.In any case, you will work with a friendly and convenient interface with maximum comfort.

After installation, start Advanced Serial Port Monitor,then connect one device to a free serial port. Select the COM number and click the "Open" button. Now, you can send data to your device and receive data from them. You can change the program mode (terminal or sniffer) from the "Mode" menu.(Step by step tutorial is here)

RS232 Terminal Mode. Our software is not just a sniffer. Using the RS232 terminal mode, you can send and receive any data from a serial port to debug and diagnose your external devices;

Flexible configuration. Our serial port monitor supports the different baud rates (up to 921600), user-defined baud rates, number of data bits, number of stop bits, different parity types, hardware or software flow control, and other. You can change all communication parameters at any time;

Any data source. The serial port monitor can send data from text or binary files. Also, you may type a data string in the program window. You can insert characters with code from 0 to 31 (0 - 2F Hex) from a popup menu;

Whether you want to check if a specific serial device is sending or receiving data as it should, or you need to see which data is going through the exact COM port, Serial Port Monitor will easily capture, log, and present the data in an extremely easy-to-read way. More than that, the advanced filtering and search options supported by the program will greatly simplify your work.

Anytime you need to read data going via a particular serial port, you can connect to it with advanced Serial Port Monitor even if the port has already been opened by another program. The software will capture data in real time and show it in one of its viewing modes (or all of them at a time, if necessary), so you can immediately compare and analyze it.

What's also nice is that the software allows copying the captured data to the clipboard or redirecting it to a file. This way, for instance, you can read and save serial input/output control codes (IOCTLs) with full details and parameters.

Another thing that you can find extremely useful about the program is its ability to sniff several COM ports simultaneously. With this unique option, you can check how your serial app communicates with multiple interfaces or devices at a time within one monitoring session. Plus, the received and sent data will be recorded into a single log using the first-in first-out method, which is especially convenient for data analysis.

The port sniffer included within the PRTG network monitor tool detects all port activity in your network, as well as your system's application usage. All the data that is being sent and received through your network's ports can be easily monitored with PRTG. With PRTG and its included port sniffer, there is no need for additional port monitoring software.

This advanced monitoring utility can capture, view, log, and analyze network data. You can use the port sniffer for data acquisition, connection & interface testing diagnostic analysis, packet analyzer and more.

If you're looking for a professional tool that will simplify the tasks of monitoring and managing your network's ports, PRTG Network Monitor is your solution. Offering both a completely free, basic edition and expanded commercial editions, PRTG Network Monitor is the right choice for all your network monitoring & analysis needs.

"I am an avid supporter of PRTG and I would like to congratulate you on this most excellent product which really works very well and is very easy to use. You have identified a gap in the market for easy "MRTG"-style traffic management, and I have to say without your product I would certainly be lost. I stumbled upon PRTG in Google whilst again looking for an easy to use "MRTG"-style traffic graphing and immediately bought it. I have also encouraged my partners to purchase the application. My business is an Internet Service Provider and we also have a Wireless Internet Service Provider Division. I use PRTG to monitor all my critical links." Eugene van der Merwe, www.snowball.co.za

"I really think that you guys have made a damn good program here, and I have never regretted buying it from you. For the past 3 years I have been using MRTG and ever since I started using it I have been searching for a program like this one. So 3 words for your team, DAMN GOOD JOB.", Jeppe Jessen, www.dns-service.dk

Microsoft Windows Server 2003 offers the standard port monitor for network print devices as an alternative to the Line Printer Remote (LPR) port monitor. The standard port monitor was introduced in Microsoft Windows 2000. In Windows Server 2003, the standard port monitor has been updated to provide better performance and more detailed device status.

The standard port monitor uses Simple Network Management Protocol (SNMP) to read the configuration of the target print device and to determine the device's detailed status. Additionally, the standard port monitor offers more accurate error reporting than the limited print error messages that are enabled by other port monitors, such as the LPR port monitor. For example, the standard port monitor supports a "paper out" error.

If the standard port monitor cannot use the default TCP ports to configure the target print device and SNMP, the standard port monitor uses the LPR protocol. (The target device must support the LPR protocol.)

For network-connected print devices, the standard port monitor is the optimal choice. In comparison with the LPR port monitor, the standard of choice in network printing for the past several years, the standard port monitor is faster, more scalable, and has bidirectional capability. By contrast, the LPR port monitor is limited in all these areas.

The standard port monitor uses either the RAW or the LPR printing protocols to send documents to a printer. Together, these protocols support most current TCP/IP printers. Do not confuse these print protocols with transport protocols, such as TCP/IP or Data Link Control (DLC).

Portmon is a utility that monitors and displays all serial andparallel port activity on a system. It has advanced filtering and searchcapabilities that make it a powerful tool for exploring the way Windowsworks, seeing how applications use ports, or tracking down problems insystem or application configurations.

Simply execute the Portmon program file (portmon.exe) and Portmonwill immediately start capturing debug output. To run Portmon onWindows 95 you must get the WinSock2update from Microsoft. Notethat if you run Portmon on Windows NT/2K portmon.exe must be locatedon a non-network drive and you must have administrative privilege.Menus, hot-keys, or toolbar buttons can be used to clear the window,save the monitored data to a file, search output, change the windowfont, and more. The on-line help describes all of Portmon's features.

Portmon understands all serial and parallel port I/O control (IOCTLs)commands and will display them along with interesting informationregarding their associated parameters. For read and write requestsPortmon displays the first several dozen bytes of the buffer, using'.' to represent non-printable characters. The Show Hex menu option letsyou toggle between ASCII and raw hex output of buffer data.

The Portmon GUI is responsible for identifying serial and parallelports. It does so by enumerating the serial ports that are configuredunder HKEY_LOCAL_MACHINE\Hardware\DeviceMap\SerialComm and theparallel ports defined underHKEY_LOCAL_MACHINE\Hardware\DeviceMap\Parallel Ports. These keyscontain the mappings between serial and parallel port device names andthe Win32-accessible names.

When you select a port to monitor, Portmon sends a request to itsdevice driver that includes the NT name (e.g. \device\serial0) thatyou are interested in. The driver uses standard filtering APIs to attachits own filter device object to the target device object. First, it usesZwCreateFile to open the target device. Then it translates thehandle it receives back from ZwCreateFile to a device objectpointer. After creating its own filter device object that matches thecharacteristics of the target, the driver callsIoAttachDeviceByPointer to establish the filter. From that point onthe Portmon driver will see all requests aimed at the target device.

Portmon has built-in knowledge of all standard serial and parallelport IOCTLs, which are the primary way that applications and driversconfigure and read status information from ports. The IOCTLs are definedin the DDK file \ddk\src\comm\inc\ntddser.h and\ddk\src\comm\inc\ntddpar.h, and some are documented in the DDK.

On Windows 95 and 98, the Portmon GUI relies on a dynamically loadedVxD to capture serial and parallel activity. The Windows VCOMM (VirtualCommunications) device driver serves as the interface to parallel andserial devices, so applications that access ports indirectly use itsservices. The Portmon VxD uses standard VxD service hooking tointercept all accesses to VCOMM's functions. Like its NT device driver,Portmon's VxD interprets requests to display them in a friendlyformat. On Windows 95 and 98 Portmon monitors all ports so there is noport selection like on NT.

After some trial and error I could get it to work.

Changed COM ports as suggested by @yvesdelbrassine, open the serial Monitor and make sure, it opens for the configured COM Port (why does platformio sometimes open the monitor for the wrong port!??)

When you managed to open the correct monitor, PRESS AND HOLD THE RST button on your esp device and THEN CLICK UPLOAD .

Once the terminal tells you it tries to connect,

release the rst button.
