The Digiboard went back yesterday. Yesterday, I traded some hardware for a Hostess board - an 8 channel dumb serial card that is supported under SCO (BTW - the SCO tech reference notes are incorrect on the address of the ports - I had to go into /usr/sys/io/sioconf.c and check the address). Anyhow - this board (even though no smarts) is working dandy under SCO. Now I get to see (if and how much) a dumb port can tie up the system! Now I can move on to multiple controllers! -- Larry Snyder SCO Xenix 2.3.2 '386 uucp: iuvax!ndcheg!ndmath!nstar!larry The Northern Star Usenet Distribution Site HST / PEP / V.22 Notre Dame, Indiana USA Home of the fighting Irish!
