Virtual Serial Ports
Almost any programming language is capable of accessing the COM ports created by the Maestro.
We recommend the Microsoft .NET framework, which is free to use and contains a SerialPort class
that makes it easy to read and write bytes from a serial port. You can download Visual Studio Express
(for either C#, C++, or Visual Basic) and write programs that use the SerialPort class to communicate
with the Maestro. You will need to set the Maestro’s serial mode to be either “USB Dual Port” or “USB
Chained”. The serial interface is documented in Section 5. For example serial code in many different
languages, see Section 5.h and Section 10.
