LCD2041 rev change

[Pistondog]

We've been using a rev 1.X (last rev 1.5) with a rabbit processor for 5 years. I need some direction migrating to the latest 2.0 rev.

using Dynamic C's 8.03 i2c.lib.

board config:
default comms to i2c via jumpers
software address to 0x50 (default)

Symptom: produces a changing display with a couple of correct chars, but mostly jibberish.

Any document summarizing changed commands and/or incompatability with above mentioned library ?

thanks for your help
