BTW do you know what flag 0x20 does for UART? 0x10 is documented but = 0x20 is not. I had a quick look at the code and AFAIK it doesn't do anything (on 9.1 = anyway). Actually at a guess I would say it's a hangover from sio(4) where 0x20 = forced the device in question to be the console. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
