The remote profile read and write commands - *Rab and *Wab -
only work in the on-line condition. The connection speed and mode
do not matter. The remote modem must be set to accept remote
configuration by executing the AT*F1 command. The AT*F0
command will set the modem up to deny remote configuration
requests. Because the modem uses the remote digital loopback
mode to request remote configuration information, the remote
digital loopback request must also be granted (AT&T4) on the
remote modem to accept the remote configuration request.
Batch mode remote configuration is a convenient feature allowing
you to pre-configure a remote modem in one of the local modem’s
user profiles and send it to the remote modem in one action. It is
particularly useful when there are many remote modems and a set
of standard configurations is available so you can store them into
user profiles. You just need to configure the remote modem into
one of the standard configurations by activating the remote
configuration once.
Caller Number Delivery (Caller ID)
Caller Number Delivery (CND), commonly called Caller ID, is a
new kind of phone service that may be offered by your local phone
company. Check your phone company for availability. You must
subscribe to it and usually pay an additional monthly service charge
for this service.
With CND service, the phone company’s central office will send the
coded caller information to the called station. This information is
sent once between the first and second rings. Your modem can
decode this caller information and present it to the connected
computer/terminal during the second ring period as part of the call
progress ring message. The modem will also report the Caller ID
information if asked by the command AT*T.
