Commands can be followed by Parameters.
Parameters are separated from Commands by at least 1 space.
Multiple Parameters are separated from each other by a comma (not a comma and a space!).
The maximum length of the list of Parameters is determined by the input buffer size of the particular Slave.
Parameters may only contain normal printable characters from the basic ASCII list.
Parameters are probably the most common cause of Execution Errors.
For instance you may accidentally omit some Parameters, or type too many.
Or you could enter a wrong value, or an ill-formatted parameter.
A Literal String can be accepted as a Parameter when it is enclosed in single ( ' ) or double quotes ( " ).
Literal Strings are case sensitive, which means that upper case and lower case characters are not the same. Furthermore you may use spaces and commas in Literal Strings.
