Yep, that's why I asked if manufacturers usually put external resistors. I tried to short all the wires together and on the ground :) from an old ISA paraller port controller card - it didn't blow up. So the message to the author of this thread: check for resistors on your mboard, if it's the old one, in series with the outputs, so that you can be sure that you won't kill the controller during experiments... 28.10.2002; 18:05:15 [SorAlx] http://cydem.zp.ua/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
