Is this true? Is there some magic config bit somewhere that will enable hidden sio support? I have some old software that talks to some old hardware over rs232 (using cuaa) and the builtin 232 port just died. I'm trying to get a Bafo BF-810 working in raw mode but haven't had much luck (open()'s and write()'s block, unless non-blocking is set, but then they return without doing anything). Any suggestions? Thanks
