3.2.7 Set String
The set string function is used to set a string, however it is restricted to six ASCII characters. Only a
few parameters implement this function.
The parameter request packet takes the following format:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
‘A’ ‘P’ ‘E’ paramID attribute Value ‘A’
Where
‘A’, ‘P’, ‘E’ are literal ASCII characters.
paramID is the parameter identifier. (see 3.2.1.2 Parameter Identifier)
attribute is the attribute identifier. (see 3.2.1.3 Attribute)
value is a value.
There is no difference between the avParamAttr_value and avParamAttr_e2value attributes. The
current recommendation is to set attribute to avParamAttr_value.
The string must be six ASCII characters long. If it is shorter the space character (‘ ’, 32, 0x20) must be
used to pad the string. Put this string in the Value bytes. Null termination should NOT be used.
The set string function on successful completion will return a successful reply packet. See “ 3.2.2.1
Success Reply Packet”.
