Hardware Description
5-6 80-99240-1 Rev. D
modem alerting, and SMS messages to be sent
simultaneously via a separate “control” port to/from the
modem. This separation of functionality is especially useful in
dormant mode, when the application and host sessions are
active, and thus the Data port appears active/in use, although
a Globalstar traffic channel is not up (no “In Call Status
Message”).
The Control port is “enabled” by asserting DTR on the Control
port.
In case of a reboot (due to fatal errors or any other reason),
the DSR line will be set inactive so that the user application
can detect a reset condition and take the necessary action.
Data Port Signals
The Data port (DP) is a hardware-flow-controlled, RS-232
level, asynchronous serial interface:
• The Data port uses the following RS-232 leads for
operations: Transmit Data (TxD), Receive Data (RxD),
Clear To Send (CTS), Data Terminal Ready (DTR), Data
Set Ready (DSR), Ready to Send (RTS), Data Carrier
Detect (DCD), Ring Indicator (RI), and Signal Common
(GND).
• The format for data on the Data port is 8 bits, no parity
and 1 stop bit.
• The baud rate is user-configurable to selected rates from
300 bps to 115.2 kbps. The baud rate is adjustable in
software.
• In case of a reboot (due to fatal errors or any other
reason), the DCD and DSR lines will be set inactive so
that the user application can detect a reset condition and
take the necessary action.
• Functionally, the Data port integrates AT commands and
alert messages as well as application data traffic.
