According to the comment in the code, you need to mmap the memory R/W in
linux for it to work. R/W permission implies full duplex the way the 
driver is
currently written.

I have not tried different mmap permissions to see if the linux bug is 
real or
still exists.  It's weird to do it that way but it's a work around for a 
bug that
may not be valid any more.  Can the person that wrote the code comment?
