Eric, Thanks for writing. As you may have predicted, It turns out the problem was that I needed to append both \r and \n to the end of the string I'm sending to emcrsh via the socket. When I wrote my question I was only using \n. I found that \r is enough in some situations, but \r\n appears to do the trick for all cases.
Thanks for the tip re threads...I think you're right that I'll need to add that in. fg On Fri, May 21, 2010 at 8:00 PM, Eric H.
