4 AT Commands
The AT (modem attention) command set is the control
interface between the SCADA application (Data Terminal
Equipment or DTE) and the GSP-1620 modem (Data
Communications Equipment or DCE).
This chapter lists the AT commands that apply to the
QUALCOMM Globalstar GSP-1620 Satellite Data Modem:
• Table 4-1, “Operational AT Commands” — lists the AT
commands recognized by the modem software.
• Table 4-2, “Non-Operational AT Commands” — lists
commands that are recognized, but not supported, by the
modem. For example, because the modem has no speaker,
the command to set speaker volume will neither set the
volume nor return an
ERROR. The command is accepted,
but performs no action.
