SwitchInspector is an easy to use application that assists you with the design, validation and auditing of your Local Area Network. SwitchInspector provides an easy and effective way to inspect a Cisco LAN switch and report which network devices are connected to each switch port. Therefore it solves the problem of having to trace cables in order to see which port is a network device connected to.

Eltima Serial Port Terminal is an ideal tool for testing, debugging and troubleshooting serial port devices. It lets you work with numerous number of ports simultaneously, both serial and virtual ones. You can easily alter baudrate, databits, parity, stop bits, flow control parameters and dynamically apply these changes to serial port settings on the go. You can always check for history of typed commands.

TVicPort are general purpose shareware device drivers.
TVicPort main capabilities are:
- direct port I/O access;
- (new!) obtains pointers to the physical memory by directly mapping it to the user process's address space;
- advanced LPT support including access to any pin on any LPT port;
- access to IDE HDDs hardware manufacturer information (HD serial number, geometry, etc.).
- (new!) Windows XP 64-bit support.

See which ports belong to which programs! Port Explorer shows all the open ports on your system and what programs own them. Along with this ability it also has many tools including a packet sniffer, bandwidth throttling and country detection to name just a few. Port Explorer has an intuitive GUI that allows you to quickly see all your network activity, and thanks to its ease of use is allowing people everywhere to do advanced network activities.

Serial Port ActiveX Control is a powerful component that lets developers quickly and effectively work with serial port. Use Serial Port component to easily communicate with external devices on RS232 connection, such as modems, bar code readers, PBX and so on. Serial Port introduces several extremely useful properties for detailed setting of serial port, numerous methods to write and read from port and events to control serial port state changes.

Advanced Port Scanner is a small, very fast, easy-to-use and robust port scanner for the Win32 platform. It is multithreaded, so on fast machines you can scan ports in very a few seconds. It has descriptions for the common ports and can perform scan on predefined port ranges.

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.

Advanced Port Scanner is a small, very fast, robust and easy-to-use Port Scanner for Windows. Powered with multithread scan technology, Advanced Port Scanner can scan hundreds of ports in just a few seconds! Also, it contains descriptions for common ports, and can perform scans on predefined port ranges.

To monitor (bi-directional) Serial communication RS-232 between two devices without physical cable, use Bill Serial Monitor. This software allows you to view, log, test and analyse the activity of the serial RS-232 port. To monitor the serial protocol of two different serial devices. DSR, CTS, DTR and RTS can also be controlled
No programming or additional hardware required !

Virtual Serial Port ActiveX Control is a powerful tool for professional developers that allows your application to create custom additional virtual serial port in system and fully control it. Created virtual serial port looks like real serial port for other Windows applications. From your application you can control data sent to virtual serial port by other applications and respond to them by sending own data to virtual serial port.

Create and manage virtual serial ports from .NET and Visual Basic (ActiveX)
Using Virtual Serial Port SDK you can create a "new" serial port on your computer. This serial port is completely controlled by your application. Other 3rd party applications can connect to this serial port and believe it is a normal serial port.
Windows Mobile/Pocket PC, Windows XP/2k/NT and Windows ME/98.
Samples in C#, VB.NET and VB6

nVision monitors your network: Windows, TCP/IP services, web and mail servers, URLs, applications (MS Exchange, SQL etc.). It also monitors routers and switches: network traffic, interface status, connected computers. You can collect network inventory and audit license usage. nVision will also alert you in case of a program installation or any configuration change. With the agent you can monitor user activity and access computers remotely.
