Perfect for analysing data on the COM ports! I love it!

Great product! I had bunch of my own software to do the same job, but nothing close to what you did. Now serial protocol debugging is 400% easier.

Your "serial port monitor" utility is AWESOME! I've place my order, (and have the eval demo running), it has saved me the cost of the purchase in less than a day of use. I'll gladly be providing an testimonial. I'm in the process control field in manufacturing industry. I'm impressed and delighted to have found your web site.

We really like version 4.07 on more contemporary platforms. As we do a lot instrumentation interfacing via RS232 (and like-standards), its a superb development and debugging tool for us.

We're grateful for the fine products!

I really like your marketing model, and from what I can tell, your software is one of those rare classes that I would call "bulletproof". I'd also call it "lean", "effective" and great!

Been a Sermon user since the early days, and have found it to be a very useful tool. I recommend Sermon to other engineers/techs whenever I get the chance.
