Rewritten the T-Balancer code to use the FTDI D2XX drivers directly instead of the System.IO.Ports.SerialPort class. The SerialPort class has some ugly problems like http://connect.microsoft.com/VisualStudio/feedback/details/140018/serialport-crashes-after-disconnect-of-usb-com-port or http://social.msdn.microsoft.com/Forums/en-US/netfxbcl/thread/8a1825d2-c84b-4620-91e7-3934a4d47330 for which no real solution seems to exist. And Microsoft doesn't feel like it needs to be fixed for years now.
