Hello all,
I've found the reason of the problem I mentioned a couple of weeks before.
The problem was I hadn't reveived 1-byte messages sent through the serial
port to a Window application running under Wine.
This byte actually came through to my program, but ReadFile reported in this
case an error, that I didn't expected, because it hadn't been in fact
there.
I analyzed only two type of errors: ERROR_IO_PENDING and ERROR_IO_INCOMPLETE. By
all other errors the input was just ignored.
Now in case when only one byte had been received ReadFile returned with the
error 87 (ERROR_INVALID_PARAMETER or something like that, I haven't the
symbolic handy now), although all parameters were actually OK.
And the received byte had been read with the correct length of received message
(1 in this case), so it could be used for as a 'normal' input.
I made a change just to ignore this error and now everything works fine.
Is it a bug in Wine or something else?
