 Hmmm... then I am in a quandry... the first two boards work fine. The
 third board probes correctly. When I attach to a device using tip...
 it connects but no data passes through... when I try to disconnect it
 hangs. 

 Here is the hung process information:
 branson  10955  0.0  1.7   260  524  pg  INE+ -          0:00.00 (tip)
 branson  10956  0.0  0.0     0    0  pg  ZN+  -          0:00.00 (tip)

 Here is the probe information:
 cy0 irq 5 maddr 0xd4000 msize 8192 on isa
 cy1 irq 11 maddr 0xd6000 msize 8192 on isa
 cy2 irq 15 maddr 0xd8000 msize 8192 on isa

 And the device I am using with tip from /etc/remote:
 kheldar|cuac20:pa=none:dv=/dev/cuac20:br#9600

 I have tried nullmodeming the port on the cy and see no data comming
 thru. I have verified the settings on the boards, and on the cards.
 I can switch cables between cards and it works as expected... so I am
 rather stumped. Any other ideas?
