I wish I had discovered this product a year ago!

... I use BrainBoxes for critical serial to ethernet application and have not had a single hiccup ...

Well I must admit to being sceptical, as we only ever found 1 [other] device that worked [reliably] and I had to leave that on a project and have never found another since. It appears on first testing that your US-101s work very well…………..

needless to say I am very pleased as it is so hard to source a laptop with on-board RS232 nowadays. Very pleased indeed! Thank you

I am most satisfied with your support. I had the problem figured out just before we hooked up, but the efforts were outstanding. ... Thank you for your assistance.
