Attached to this message is a patch (bm-flow.patch) which turns on hardware
serial flow control. Please apply it when in the BrailleDrivers/Baum/
subdirectory. It's based on 3.7.2 (although it'll probably also apply without
problems in the latest development stream). Since it's just a test, it only
turns on flow control when using serial I/O. Please let me know what happens
when you use it. Remember that it's only a test (which may, in fact, cause more
problems than it may solve) so be sure to have a way to get back to what you
already have that works.

I don't know how new to Linux you are. Just in case you need to know how to
apply the patch, here are the steps:

   cd /path/to/brltty-3.7.2
   cd BrailleDrivers/Baum
   patch -p0 </path/to/bm-flow.patch
   cd ../..  # back to brltty-3.7.2 top-level
   make
   ...

IT'd be great if you could do that. Just collect the data and forward it on. 
We'll be glad to analyze it.
