Serial Port Monitor is a system utility for exploring the way OS works and monitoring how applications use ports. It can effectively be used for monitoring serial data exchange between serial devices and any Windows application, debugging computer connection with peripheral devices using COM port, for solving problems with serial (RS232/422/485) data communication control networks and devices, for software and hardware testing etc.

ser232mon can monitor the RS232 COM1,2,3,... and show the datas when the Windows application control the RS232 COM port,such as modem mini-ATS, projector etc.

Shared Serial Port - advanced utility to share real serial ports between applications so that all applications will receive/send data from/to real serial port simultaneously. Shared Serial Port creates virtual serial ports, which are same copies as real ones. Any virtual serial port will have the same name as the real one and any number of applications will be capable of using it at the same time.

Serial Port Sniffer is a powerful advanced ActiveX Control that allows your application to sniff (fully monitor and edit data flows) serial port in your system. Serial Port Sniffer ActiveX Control detects all serial port activity in your system, all applications that work with serial port and all the data that is being sent and received can be easily monitored with Serial Port Sniffer ActiveX Control within your own application.

Serial Port AX Control is a powerful ActiveX component that lets developers quickly and effectively organize work with serial ports. Serial Port AX Control makes communicating with external devices on rs232 connection really fast and reliable. Serial Port AX Control offers control of such devices as modems, bar code readers, navigational devices and others through a serial port. Includes examples for Microsoft VC++ and Microsoft Visual Basic.

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 Driver XP (VSPD XP) creates virtual com ports in your system and connects them via reliable virtual link, which emulates real null-modem cable. With VSPD XP you can connect one application to another using virtual serial ports pair. Applications will be able to exchange data. The latest version of VSPD XP now supports full baudrate emulation. New manual and examples are available.

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.
