Getting Started

Monitor was designed to verify the status of your connection to the internet.  Originally intended for use with the 3Com OfficeConnect Remote Dual Analog router, it can also be used by other routers equipped with a console (serial) port.

When started, Monitor will minimize itself and place an icon in the taskbar.  Moving the mouse over the Monitor icon will show what % the failure meter is currently at.  Right-clicking the icon will allow you to bring up the main program screen.

How It Works

Monitor will ping the primary IP address at the interval you specify.  On a failure of the primary address, the secondary address will be tried.  A bad response from both addresses will increment the failure counter.  If the retries value of failures is exceeded, the failure command string will be sent to the router and the failure count will be reset.


Failure Command String

Enter the commands to be sent to the router.  The carat ( ^ )  character can be used to generate control characters, i.e. ^m = ENTER.

To cause the 3Com OCRDA router to disconnect, use the string:

^M^M^Mhangup interface mod:1^Mhangup interface mod:2^M

A delay of 250ms will occur after any control character is transmitted.

Please note that the output comm port is configured to 9600,8,N,1 (non adjustable).

Support

Since Monitor is provided as freeware, there is no support.  However, you can email me at john@hutchey.com and I may give an answer.

If you need custom modifications, etc. I would be happy to quote you a reasonable price.
