--- Comment #3 from Sergey Lepeshkin LepeshkinSN@gmail.com --- Hi!
I just want to tell community about my solution to related problem.
Problem: Program tries to automatically find serial port, which is emulated by Prolific pl2303 chip. Search is done by inspection of hardware id for every port, listed in registry.
Solution: Hardware identification must be added to registry. I’ve just copied related records from windows xp registry to wine, and all works fine.
My pl2303_wine_reg.reg file is attached above. It adds support for COM1 as PL2303 with hardware id Vid_067b&Pid_2303
