Back in 2005 we had a really bad issue with ZModem to a barcode terminal over an USB2Serial adaptor and Chuck helped us as a consultant.<p>I&#x27;ve just dug out the old emails we&#x27;ve exchanged back in the day and I remember how great it felt when after only two days, he solved the problem we&#x27;ve been working on for weeks.<p>I was so happy to finally see our problem go away.
