Serial Port Monitor ActiveX Control

Serial Port Monitor ActiveX is a versatile and useful component that will empower your application with the power to fully monitor all serial port activity in the system.

The component offers you a wide set of features to check the state of the serial port, intercept all signal line events (Ring, RTS, DCD, DTR, RTS, etc.) and control functions (Handflow, Baudrate, Timeouts). Rich set of methods, events and properties will help you track down serial port activity to the smallest detail.

With Serial Port Monitor ActiveX you can:

Monitor already opened ports

Start monitoring the port that has already been opened by another application. Serial Port Monitor ActiveX will tell you which application exactly has opened the port. You can stop monitoring the port the same way, without the need to close the port first.
