The initial Merlin Modem Manager screen displays numerous modem p arameters. These

registered. The modem's status is updated every 3 seconds.
Setting Description
Cellular Signal
Present When checked, it indicates that the modem has identified a
cellular signal.
CDPD Service
Detected When checked, it indicates that the modem has identified and
is synchronized to a CDPD signal in the area.
Modem Ready
Registered When checked, it indicates that the modem has successfully
registered with a CDPD service provider in the coverage area.
When the indicator is lit a working data connection exists and
can be used by other applications to transmit and receive
data. Until this checkbox is selected, the modem can neither
transmit nor receive data.
RSSI Measures Received Signal Strength from the wireless base
station. These values range from one to ten bars. The greater
the number of bars, the better the performance of the modem.
Error Detect When checked, it indicates that a large number of errors have
been detected by the modem. Under these circumstances the
modem may continue to operate but with a severely reduced
performance, caused by the increased likelihood of
connection retries and data errors when communicating with
the wireless base station.
System Busy When checked, it indicates that the currently detected CDPD
system is busy. The modem may continue to operate but at a
decreased level of performance.
Wireless Provider Displays the CDPD channel’s System Provider’s Identifier.
