Here is a shot in the dark It almost sounds like issue with the SPACE character code... try just punctuation with no space, like a comma perhaps?

Gunner - LOL! I spent like 6 hours trying different combinations, that was one of them, I can use one word like "hello" but "hello world" locks up the EZ-B, even "helloworld" or "hello,world", I started thinking it was the length of words, but there's no pattern with that, something with the sendserial strings in ARC.

Even the LCD like I mentioned before has the same issue, i'm sure it's a simple bug that DJ will have a fix for in notime, but for now I had to resort to another MCU for the time being...

Possibly just hates multiple syllables so I guess "supercalafragalisticexpialadoshus" probably won't work either

LOL that could be it, i'm suprised I missed it though last week with the LCD module...
