Send data (4-digit Hex) The data specified in hexadecimal here will
be converted to ASCII and the number of
bytes specified in S+3 will be sent.
Note 1. Set the number of send bytes to twice the number of bytes in memory. This is necessary because the
data is converted to ASCII data before being sent.
