DART 200 CDPD Modem User’s Guide 4 Broadcast and Multicast Operation

Sierra Wireless, Inc. 4-4

Some software stacks, used when the DART 200 operates in Serial Line

Internet Protocol (SLIP) mode, only receive broadcast messages

(including multicast) on a specific IP destination address, specifically the

point-to-point NEI. To provide for this limitation, the DART 200 permits

specifying whether or not the received destination IP Address (multicast

address) is replaced with the active point-to-point NEI before the

received packet is passed across the SLIP interface to the software stack.

This feature is implemented by using the AT*G command. AT*G1

(default) causes the received destination address to be replaced as

described above. AT*G0 passes the received packet across the SLIP

interface to the TCP stack unmodified, with the destination address being

that of the Multicast NEI.
