Pavel,

do you have a scope? Can you look what physically happens on the serial
line? Does the program via wine actually write out the challange? Does the
the device react to the challange? Whats the delay between challange and
response? 

I suspect something with our wait implementation to go wrong. The program
immediate does a read after the write, and doesn't repeat the read if 0
characters are read. So if the device reacts slow, the read will be to
early.

Can you try to put a Sleep() between the Readfile() and the Writefile() in
the windows program?

Bye
