correct, the AMIS−49587 acknowledges with an <ACK>
character. In other cases, it answers with a <NAK>
character. In case of <NAK> response, or no
acknowledgement from AMIS−49587 in the Tack time−out,
a complete sequence must be restarted to repeat the frame.
correct, the base micro acknowledges with an <ACK>
character. In other cases, it answers with a <NAK>
character. In case of <NAK> response from the Base Micro,
the AMIS−49587 will repeat the frame only once after a
delay corresponding to Twbc (Wait Before Continue). A non
response from the base micro or a framing error when an
length and the checksum are both correct, the local frame is
taken in account otherwise all previous characters are
