The {C setting is not automatically written to EEPROM. Send &W to maintain the S registers after
a reset.
3.
Enter the CID number of the originating Modemulator into the answering Modemulator’s dialing
directory
Connect a computer serial port to the answering Modemulator Terminal port with a serial cable.
Run a terminal application on the computer to facilitate sending commands into the Modemulator.
to enter the same CID number that was programmed into the originating
Modemulator in step 1, along with the port number and IP address of the originating Modemulator.
Example:
AT{Y=18005551234:8888:172.18.3.2
The number written by the {Y command is automatically stored to EEPROM. It does not require
you to send &W.
4.
Enable CID in the answering Modemulator
to enable CID in the answering Modemulator.
Example:
AT{C1&W
The {C setting is not automatically written to EEPROM. Send &W to maintain the S registers after
a reset.
5.
Caller ID Screening is now operational
Steps 1 and 2 configure the originating Modemulator to always send its CID number when originating a
connection. Steps 3 and 4 configure the answering Modemulator to always require a valid CID number
when answering a connection. If a valid CID number is not received during a connection handshake, the
connection will fail and the originating Modemulator will display
REFUSED
.
In a peer-to-peer system any Modemulator can originate or answer a connection. In that case, it
is recommended to set up each Modemulator as both CID originator and CID answerer.
Example:
AT{C0&W
