5.5 Communication Error Handling
If a communication error is detected by the scale either through parity bit (optional) or a data framing
error the scale will respond with an ASCII ‘!’. The only other error mechanism that has been
incorporated into the scale is the unrecognized or unsupported command response message, in this
case the scale responds with an ASCII ‘?’. Upon error discovery the host can then decide which course
of action to take to re-affirm or re-establish proper communications with the scale.
