[Wine] Mac Wine 1.1.35 COM port can't exceed 38400 baud

[bortoni]

I am trying to run a serial port communication app under wine. On the mac side I run USB->Serial device (KeySpan). 

Using and app like TeraTerm, I'm able to see the com port and send and receive data. However, I can't go beyond 38400 baud. Any attempt to go beyond that places the baud rate to 9600 regardless of what is selected.

Any suggestions? Someone of the codeweaver's forum said the following on this issue:


> 
> "Under windows the baud rate etc is set by creating a device control block (DCB) , and using buildDCB(string,DCB) to set values in the DCB.  
> The value in the dcb at this point for baud rate is 57600; 
> 
> This is followed by SetCommState(handle,DCB).  There is no error return, but it appears that this function is not working, because if it is followed by the function GetCommState(handle,DCB), the DCB reports the baud rate as 9600.

Any help would be appreciated.
