If you are running a 2.9BSD kernel with networking, you may have noticed

inability to deal with a USIZE > 16.  The following change to setup.c in
/usr/src/bin/adb will correct the problem.

< current -- setup.c -- modified >

< 				uar0 = ar0 - 0140000 + (unsigned)corhdr;

> 				uar0=(POS *)&corhdr[(int)(ar0-(POS *)0140000)];
