Spec081 (Token-Passing Data Link Layer Specification) para 5.2 says:
While several errors are possible during message reception, only three are fatal: (1) a gap error;
(2) loss of carrier; or (3) a communication error receiving the Delimiter, Address or Byte Count. A
gap error indicates that the transmitting device malfunctioned mid-message. ... All of these error conditions are fatal, aborts the message reception and discards any portion of the message received ...
I take this to mean that a slave should not reply at all. Does anybody else have an opinion?
