Glad my Serial stuff is proving useful. A couple of things to try:
Change the end-of-line character for sending data. My stack allows
three different options and it may be that the brick won't respond
until it gets the right one. (I use a serial device that ignores all
incoming data until it gets LF).
The other thing is to read for a set period instead of until eof, just
in case it is a timing thing and the response is being delayed.
