When developing embedded SCADA applications, developers
can use off-the-shelf protocol stacks or write their own. Any
standard RFC 1661 or RFC 1662 compliant stack should
work.
Interoperability with Different Operating Systems
The GSP-1620 modem uses standard networking software to
establish, manage, and tear down the PPP session. The
modem has been tested with the following standard operating
systems:
• Windows 95/98/2000
• Windows NT
• Macintosh OS
• UNIX/Linux
Note
For Windows 2000, a possible software driver problem exists. For more
information, contact QUALCOMM Globalstar Customer Service, as
described in Chapter 10, Product Support.
IP Addressing for the GSP-1620 Modem
For packet data, the OEM or Service Provider must choose
either a dynamic or fixed Internet Protocol (IP) addressing

modem:
• If the modem is expected to be mobile and roam between
Gateway service areas, a dynamic IP addressing scheme
should be used. A new IP address may be assigned to the
terminal equipment whenever a new packet data call is
set up.
• If the unit is “fixed” in its position and no mobility is
involved, either a dynamic or fixed IP addressing scheme
can be used. However, if the unit is “fixed” in its position,
