2. Can I get old programs to run under Windows 10?

Yes, you can get old programs to install and run using the Program Compatibility Troubleshooter (msdt.exe) wizard which will allow Windows to run as an older version of Windows. So, if a program fails to run or install natively in Windows 10 you can fool it to think it us running on an older OS. See the Compatibility tab of the properties of an Program file or shortcut to a program file. If a program fails to install, set the Compatibility mode to older Windows for the Setup.exe program on th CD/DVD. In some cases, it may be better to install Windows 10 32 bit for better compatibility with older programs and games.

You can install Hyper-V (see Programs and Features) or Virtual Box to run and emulate another version of Windows hosted on your Windows 10 system, but will need a Windows disc or image to install the other OS.
Hyper-V supports Windows Vista SP2 (2006), Windows 7 SP1 (2009), Windows 8 (2012), Windows 8.1 (2013), Windows 10 and Windows Server.

See this article on Serial Port Programming in Win32 or Serial Port Programming with .NET. If your PC only has USB ports, try Developing applications for USB devices.
