Re: making mods to posix-tty

Thanks John.

Once I knew to look in system instead of src everything seems to work  
OK although I haven't tried to install the newly built version.

Hey, I can hack the compiler now !  ha !

Interesting note about the lame posix limit.  I just assumed that the  
spec had since been revised to include the new rates.  Not going to  
115200 is kind of silly.

Thanks for the note about wordToSpeed, I can run with that.  I'm  
really after 230400 :-)

I'm still going to play with the compiler though.
