You kidding right? VB and real-time? ROFL... I never had sooooo much laugh in my life! You either don't use VB or you don't write real-time anything. Besides, what RT are you talking about on windows? Or you using specially modified versions of it for soft RT (windows by definition is incapable of hard-RT)? As Austin said, Wine has number of issues with serial ports. It's a hit and miss. My suggestion write native Linux app instead.
