Verifying signal strength
The Wireless MultiModem establishes a call if the
signal is sufficiently strong. To verify the signal
strength, do the following:
1. Using the
Hyperterminal
program at the
computer to which the Wireless MultiModem
is connected, type the AT command AT+CSQ.
A value for the received signal strength will be
returned.
2. Verify the result with the following chart:
