Known issues:
-------------
Currently two know issues exist; the StringBuilder class has
problems that cause string concatenation to freak out. I'll be looking
into this shortly. In the mean time, try alternative methods (like
individual print() calls to print a compound message). The Super Serial
Card driver has problems with XON/XOFF flow control. It might be a
problem with my USB serial dongle. I tried hardware flow control, which
worked except characters would get truncated when it halted the receiver.
XON/XOFF should work, but doesn't on my setup. I'll try to connect to a
real serial port on a Linux box to see if it works any better.
