#176067 - ZERO Responding to: ???'s previous message |
My question is, what is an acceptable percentage of error in Baud rate calculation, that may be used to establish the reliability in use, of a particular serial port set-up?
I insist on zero (OK +-0.2% or so). The reason being that, while some total leeway is allowable (+-2%?) for the transmission who knows if "the other end is "on the nose". I have had actual cases of working with equipment that was off by a couple of percent to either side and if, in those cases, I had been off as well (to the other side) there would have been failure.
