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.

Configurable UDP and TCP port forwarding.
Define IP address ranges to allow or block for each port being forwarded.
Have program forward multiple ports simultaneously.
View the current data throughput speed of each port forwarding operation.
Have program log connection events to a text file.
Run program without installing (if desired).
Bounce connections back to connector (on same or different port).
100% freeware.

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

SRedirect is a command line utility that allows a remote TCP/IP connection to a serial port. SRedirect redirects all RS-232 data from a TCP/IP port to and from the local serial port. SRedirect creates a server for ONE local serial communications (COM) port. SRedirect allows connection of a client application. SRedirect transfers data in both directions between the connected client and the local COM port.

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.

Look RS232 is a tool for debugging computer connection with peripheral devices using COM port, such as modem, mini-ATS, projector etc. Its easy to use interface guarantees an easy work with Com-port. Look RS232 can send data through COM port, receive data from an outer device through COM port, it has port indication as well. Look RS232 supports connection at the standard speed of 110-15200 kbit/s, it supports commands of COM port program control.

Virtual Serial Port ActiveX allows your application to create additional virtual serial port in system and fully control it. Created virtual port looks absolutely like a real one for Windows applications. You can view parameters information of a virtual port, set by other application, view and control from your application data sent to virtual port by other applications and respond to them by sending your own serial data to virtual COM port.

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.

PortMarshaller is a software-based TCP/IP port forwarder. The software accepts connections on a particular TCP port, and establishes connections to a different TCP port to fulfill requests.

Monitor multiple web or TCP servers (http, https, ftp, pop3 etc.) Receive email notification by email or pager if any can't server can't be reached a number of times in a row. A1Monitor can reboot your NT server or run a batch file or program for you.
