write(), print(), println() now return size_t (and don't use negative values to signal errors). Print adds writeError() for checking for write errors, clearWriteError() to reset the flag to false, and a protected setWriteError() for signalling errors. http://code.google.com/p/arduino/issues/detail?id=598
