(0 or 1) Sufficiently large email messages may need to be broken into multiple SMS messages. When this occurs, the individual SMS messages can optionally have sequencing information added using the SMS sar_ fields. This produces a “segmented” SMS message which can be re-assembled into a single SMS message by the receiving terminal. Specify USE_SAR=1 to indicate that this sequencing information is to be added when applicable. The default is to not add sequencing information and corresponds to USE_SAR=0.
When USE_SAR=1 is specified, the REVERSE_ORDER option is ignored.
