All parameters are specified in hexadecimal unless otherwise specified. Where
decimal is specified, it is indicated by BCD.
The command code and text for the command are stored in memory as oper-
ands and the transmission is executed using the required parameters. The spe-
cific method depends on the programming method being used. Prepare the
transmission data from the command code to the end of the text (with the data
determined by the individual command), and execute the library function or
driver call for message transmission. There are two bytes available for the com-
mand code and 0 to 2,000 bytes for the text.
