I fixed that some time ago to support more boards > as you can plug in. 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? - branson ------------------------------------------------------------------------------- Branson Matheson " If you are falling off of a mountain, System Administrator You may as well try to fly."
