Sierra Wireless DART 200 CDPD Modem - Manual (Page 20)

DART 200 CDPD Modem User’s Guide 1 Introduction
Sierra Wireless, Inc. 1-2
From a networking perspective, the modem has complete built-in
Transmission Control Protocol (TCP), User Datagram Protocol (UDP),
Serial Line Internet Protocol (SLIP), and telnet protocols. Network
communications can be achieved without the attached end-user device
having to provide an integrated TCP or UDP capability. Select the
desired built-in protocol included in the DART 200 by using the
appropriate AT dial command and begin your data transfer. The end-user
can put the DART 200 in SLIP mode, providing an external software
stack, if desired.
A power cord with connector is supplied with each DART 200, and one
copy of this User’s Guide is included with each order. A power supply
and cellular antennas are available as options at additional cost.

Migration considerations

Friends Only mode or Auto SLIP restart, some alteration can be required.
