What is Devtracer?

DevTracer is a fast and effective tool for collecting trace output. It can be used with many development platforms for Microsoft Windows, like Microsoft Visual Studio and Visual Basic 6. It can also be used with scripting languages like VBScript (Windows Scripting Host), and with web applications (ASP, ASP.NET)

Why Devtracer?

Some benefits when using DevTracer:

Create and collect trace output for desktop applications, distributed applications, web applications, script ...
Unicode support
Tracing across process boundaries
Monitor tracing across network
Can be used with .NET and COM (Microsoft Component Object Model) compatible applications
Does not decrease the performance of the application
Applications using DevTracer do not depend on DevTracer, i.e. they will still run on machines without DevTracer (or part of it) installed.
Monitor several applications simultaneously. For example: if you develop an ASP.NET application and a Web Service consumed by the ASP.NET application, both can be monitored at the same time.
Who can use DevTracer?
Basically every software developer writing software for Microsoft Windows can use DevTracer. It does not depend on how you develop your software. It can be used with all development tools targeting the Microsoft .NET platform, and with all tools that support COM (Component Object Model).

DevTracer is also a great tool for testers. Whenever they find a bug, they can use DevTracer to create some trace information. This information they can send to the developer along with the bug report, helping the developer to find the cause of the bug.

Serial Port Redirector is used to connect a serial application to a remote TCP socket. This allows you to utilize modern hardware COM servers without changing your software or exchange data between a TCP/IP application and an old-fashioned program that can only connect to a serial port.

Serial Port Redirector creates a two-way bridge between a serial application and a specific TCP port at a specified IP address. This is done by creating virtual COM ports. When a serial application connects to one of these COM ports, a connection is established to a specified host and all the data from the COM port gets redirected via the Internet or a Local Area Network. The program receives data from network and redirects them to virtual COM port. It works transparently for serial apps. They use virtual COM ports as if they were connected directly to your hardware devices. With Serial Port Redirector, you can easily control remote hardware COM servers via a TCP/IP network from your serial application designed to work with locally connected devices only. Now you can access a router console, work with sales terminals and barcode scanners and more.

Modern electronic instruments may not support COM ports. They are plugged into USB or network adapters and can only send/receive data via TCP/IP networks. If you wish to use your old serial applications to analyze the data or control the devices, you will need a tool like Serial Port Redirector. Serial Port Redirector is compatible with the vast majority of hardware COM servers. Moreover, it can actually enhance their functionality. Normally, hardware COM servers are equipped with some basic software applications. For example, they are usually supplied with a terminal program that uses the Telnet protocol. While this works OK in a simple interactive mode, raw data transfers get scrambled due to an incomplete protocol implementation. Serial Port Redirector solves this problem.

Serial Port Mapper allows you to map any serial ports to any other serial ports. For example you install additional serial port expansion card to computer as COM7 serial port but your favorite software can work with COM1...COM4 ports only. To resolve this problem you can use Serial Port Mapper to map new COM7 port either to COM1 or to COM2...COM4. Now your software can open COM1 port (or COM2...COM4) but actually work with new COM7 port. Configuration via command line interface is available as well.

Serial Com Port Monitor displays, logs and analyzes all serial data exchange between serial devices and any application. This tool is ideal to monitor serial communication, all data that is sent to and received from serial RS232/422/485 port, all events that are sent to port by an application and the status of these events. Different types of monitored data representation, easy to navigate and customizable interface supplemented with flexible com port configuration and terminal emulation mode make Serial Com Port Monitor the best choice for professional developers. You will be able to monitor, track, log and analyze the work of any application or serial device. Serial Com Port Monitor connects to a com port, opened by any application or hardware and starts monitoring it. From now on, all the data that goes through the monitored port will show in this monitoring tool. Everything is captured in real-time, so you can track down problems immediately. Moreover, you can redirect all the monitoring data to the defined file or you can copy all recorded data to a clipboard. Serial Com Port Monitor gives you the ability to intercept and record all serial input/output control codes (IOCTLs), tracking their full details and parameters. After the monitoring period is over, you can save the session and load it next time whenever you need it. Also, Serial Com Port Monitor provides you with the ability to send data of various formats: string, binary, octal, decimal, hexadecimal, mixed. More than that, you can change the type of data being sent immediately without closing the session. The same way during one session enabled, you can modify serial port settings, such as stopbits, flow control, parity control, data bits, highlighting, etc. whatever you need to follow the work of serial port. Serial Port lets you choose monitoring filters, thus saving your time and letting you track down only those specific events you are interested in.
