When the MESSAGE has a wrong <CRC>, the
SLAVE will respond with the following string:
<STX>+<ADR>+<NACK>+<ETX>+<CRC>
where <STX>, <ADR>, <ETX> and <CRC> have
the meaning previously discussed, while <NACK> =
0x15.
When the MESSAGE requires an access to an un-
known window, the SLAVE will respond with the
following string:
<STX>+<ADR>+<'2'>+<ETX>+<CRC>
where <STX>, <ADR>, <ETX> and <CRC> have
the meaning previously discussed.
When the MESSAGE is a writing command to a
window, but the data is of a wrong type, the SLAVE
will respond with the following string:
<STX>+<ADR>+<'3'>+<ETX>+<CRC>
where <STX>, <ADR>, <ETX> and <CRC> have
the meaning previously discussed.
When the MESSAGE is a writing command to a
window, but the data has a value out of the admit-
ted range, the SLAVE will respond with the follow-
ing string:
<STX>+<ADR>+<'4'>+<ETX>+<CRC>
where <STX>, <ADR>, <ETX> and <CRC> have
the meaning previously discussed.
When the MESSAGE is a writing command to a
reading only window, or it is a reading command of
a writing only window, the SLAVE will respond with
the following string:
<STX>+<ADR>+<'5'>+<ETX>+<CRC>
where <STX>, <ADR>, <ETX> and <CRC> have
the meaning previously discussed.
