Responding to: ???'s previous message
Michael Karas said:
It is similar to I2C but has a substantial improvement for use in going over cables and board to board. SMBus protocol calls for a hold time of 300nsec on the SDA line...

Doesn't it also specify timeouts for recovery from various possible "lock-up" scenarios...?
