“EZTap is a terrific value for the money, and makes it so much easier for me to send an intercept kit to a remote location for an untrained user. I’m going to have to buy at least one more because mine is always loaned out.”
– Ken Roach Rockwell

“I have been around long enough to have been one of the very first to use RS-232 in an industrial application.

Of all the ‘protocol analyzers’ or serial port ‘taps’ I have used over the decades, yours is by far the most well-designed and useful. Keep up the good work.”

“Using EZ-Tap and EZView I was able to find the problem in my software and fix it. In fact, I just emailed our new software to our customer. It’s been a long day, but I got it done thanks to your help and your great product.”
– Bob Crawford
Design Engineer

“I just wanted to say thanks for for your E-Z-Tap Pro serial sniffer. I have worked with process communications for nearly 45 years and have made my own tap hardware to save a few $$. Passive taps do the job but the E-Z-Tap Pro takes serial sniffing to a whole different level. I have only had the hardware for a few months but it has bailed me out several times in the interim. I love the fact it tracks all the control lines and time stamping is a real bonus.”
