Serial Port Monitor ActiveX Control 4.0
Serial Port Monitor ActiveX Control is a powerful and unique ActiveX control that can be easily embedded into your application to sniff (fully monitor) any serial port in a system.
This component offers a wide range of events, properties, and methods to check the state of the serial port, intercept all signal line events (Ring, RTS, DCD, DTR, RTS) and control functions. Additionally, it provides low-level access to serial port via standard IRP major functions and IOCTL requests. Serial Port Monitor ActiveX Control will help you detect all serial port activity in your system, determine all applications that work with serial port as well as control serial port directly within your application (open/close serial port) without being detected. This versatile component can be easily extended with your own functionality, delivering new creative opportunities to serial port application development. Version 4.0 is completely compatible with Windows Vista.
