“Daniel Bright and I wanted to express our appreciation for your software assistance to get the SentryPlus to function with the XP SP3 system. It is up and running fine thanks to the support. Although Daniel and I cut our teeth on DOS & COM Ports, the SentryPlus set up caught us off guard. The problem ended up being an unused dial up modem had grabbed COM3 on restarts. We disabled the modem and it came up fast and fine. Thanks again and our regards.”
