According to the "D2XX Programmer's Guide"
(https://www.ftdichip.com/Support/Documents/ProgramGuides/D2XX_Programmer%27s_Guide(FT_000071).pdf), 
there are two functions that can take the EV_RXFLAG (one of them seems to be
Windows specific):
FT_W32_SetCommMask (Supported Operating Systems: Linux, Mac OS X, Windows)
FT_W32_GetCommMask (Supported Operating Systems: Windows)

Does it make sense to try adopt the 'alternative driver' - D2XX for FTDI
devices and a shim layer between the FTDI's Linux D2XX driver and application
running under Wine?
(https://github.com/brentr/wineftd2xx)

If there is a way to use VCP through D2XX driver (emulate a VCP interface
through it), then maybe this one and other similar applications could work
(probably only for FTDI's chips, quite common anyway).
