For AWD there's a private function:
awviSetLogicLevels(1.0 4.0)
which sets the low and high voltage levels - but it's private. However, since AWD is going away in IC610, I don't see much danger in using it...
For wavescan there's cdsenv settings:
Code:wavescan.trace dToAHiVoltage string "5.0"
wavescan.trace dToALoVoltage string "0.0"
wavescan.trace dToAXVoltage string "(vhi + vlo)/2"
wavescan.trace dToAUnit string "V"
I've not tried the wavescan settings, but I think these should do what you want.

Andrew.
