>Well, it won't return for at least one millisecond. :-) Seriously, "delay"'s accuracy is not guaranteed, and at best has a resolution of 1/60th of a second. If you need guaranteed millisecond timing, you shouldn't be using AppleScript. Heck, you probably shouldn't be using a normal consumer OS.
Real-time AppleScript won't be easy. But anything on a modern Mac that attempts to talk with a simple piece of hardware, like my new Analog Devices chip that needs to be programmed with an I2C serial interface, is a pain. Have you considered a Mac SE/30 with its easy to use RS422 serial ports? 128 kb/sec is achievable with control over the speed. MS Excel 4 provides an entry to CODE modules for the interface.
I'd edit "normal" to "modern" in Chris' comment. What scriptable software are you planning to use?
