No at all 38400 : 20 = 1920
Right is 115200 : 20 = 5760
5760 don't work although it is a possible dividor 20!

9600 works also fine.
115200 : 12 = 9600 but it works whit 115200 and divisor 0!!!

Yes, I can't get 5726 from 38400, 57600 or 115200 at all, but it 
works in Windoze very well. I think it is a Way to get 5726, but 
Gates don't give the source.

I have tryied some possibility.
Take a Look on Attachment Wine-COM.tgz, please. 

Thanks much, I am waiting for resolution.
