You mean he made it work in USB mode? It has always worked (sort of) in RS232 mode. I say "sort of," because the Dectalk USB isn't 100% backwards compatible with the Dectalk Express. So, you get a few "command error in command" messages at startup, and the pitch and speed randomly get changed. This has been going on for years.
