Actually the comment for flags=0x40 seems like it might have a typo. Should it read "Do not reserve ...." or is there a complete other sentence missing that starts "Do not"? "Do not reserve this unit for low level console operations. (Makes kernel debugging easier at the expense of normal serial console support.)" ??? Would a low-level console operations include system messages written to /dev/console? -Chris # $Id: LINT,v 1.331 1997/05/06 18:24:17 fsmp Exp $ # 0x40 reserve this unit for low level console operations.
