The following table illustrates the function of each of these parameters with the base
parameter (MM.PPP) identified as S.MM.PPP.
S.MM.PPP : Status and Command
This parameter contains the command code (bits b7 to b0) and status (bits b15 to b8)
information.
Possible values for Status
are
:
Possible values for Command (bits b7 to
b0)
are
:
S.MM.PPP + 1
:
Destination IP address
(wwwxxx)
This parameter is used to specify the first two octets (wwwxxx) of the destination IP
address.
S.MM.PPP + 2 : Destination IP address (yyyzzz)
This parameter is used to specify the last two octets (yyyzzz) of the destination IP
address
.
