Was just testing the gateway serial module in a 7.7.4 gateway with Java 1\_8.71, WIN 10. Encountered this issue. Serial Module 2.7.4 (b2015033012)

I think you’ll need to upgrade at least your serial module to the one released with 7.7.8.

Oops, I thought 7.7.8 was released. I think 7.7.7 will also work if you don’t want to run a beta version.
