RTS/CTS

Good day!

A couple of wine-users have said Wine doesn't work RTS/CTS right any
more, so I did a +comm,+file trace of juno, and was rewarded with this:

trace:comm:SetCommState handle 224, ptr 0x403f0578
trace:comm:SetCommState bytesize 8 baudrate 115200 fParity 0 Parity 0 stopbits 1
trace:comm:SetCommState ~IXON ~IXOFF
trace:comm:SetCommState CRTSCTS
trace:comm:SetCommState ~CRTSCTS

Does something look wrong about that, or am I just seeing it crosseyed?

In GetCommState we have this:

if (port.c_cflag & CRTSCTS) {
    	lpdcb->fDtrControl = DTR_CONTROL_ENABLE;
    	lpdcb->fRtsControl = RTS_CONTROL_ENABLE;
    	lpdcb->fOutxCtsFlow = 1;
    	lpdcb->fOutxDsrFlow = 1;
    } else

And in SetCommState this:

if (	lpdcb->fOutxCtsFlow 			||
    	lpdcb->fRtsControl == RTS_CONTROL_ENABLE
    )
      {
        port.c_cflag |= CRTSCTS;
        TRACE("CRTSCTS\n");
      }
    
    if (lpdcb->fDtrControl == DTR_CONTROL_ENABLE)
      {
        port.c_cflag &= ~CRTSCTS;
        TRACE("~CRTSCTS\n");
      }

So I guess if you want to turn off CRTSCTS,

GetCommState(handle, lpdcb);
    SetCommState(handle, lpdcb);

would about do it.  I don't know what fDtrControl is 'spoze to do, but
shutting off flow control entirely seems a bit extreme.  Juno apparently
asks for it by name, CRTSCTS was not on when it did GetCommState, but it
asked for flow control, too.
