ATCommands
REASON NO NAME = <message> where message is ‘Out Of Area’ or ‘Private’ is displayed if the network does not provide a name
QUAL = Long Distance | is displayed if the call is long distance |
REDIRECT = <message> | where message can be ‘Call Forward’ or ‘Call Forward: |
| First Number Busy’ or ‘Call Forward: First Number |
| Didn’t Answer’ if the call has been |
| another number. |
LOOKUP NAME = ttt..ttt | where ttt...ttt is the name looked up by the modem in its |
| security database. |
CALLBACK NMBR = nnn nnn where nnn...nnn is the phone number to use to ring the caller back (which may be different from the number he dialed in on)
These messages are only available if the Telecommunications Carrier inserts them.
A further option of AT#CID2 is available. This tells the modem to send the entire CALLER ID message back to the host computer in hex format to allow the host software to decode it.
The modem also supports the following commands:
AT#CID? | Which returns the current setting of the #CID command |
AT#CID=? | Which returns the available settings of the #CID |
| command (0,1,2,3) |
Integrating Caller ID into the Security Database
Enter the Security Menu by typing AT#S.
You will then be presented with a request for a Password. If you have not specified a password then key ENTER, else type in the password.
The Caller ID status is displayed at the bottom of the Security Menu. If Caller ID is enabled you have the choice of Excluding Callers who are unknown and Accepting Callers who are unknown by using the ‘T’ command. The T command toggles the option.
To enter a phone number into the security database use the ‘2’ command. The modem will prompt for the name of the user you wish to identify. Enter the name and then skip the Password and Options fields by pressing ENTER for each. The modem will ask for a Command or Phone Number. Simply enter the phone number you want to recognise at this point.
If you wish to identify a range of numbers with the same user name, as in the case of a business with a large number of phone numbers, you can use the * to match any digit in that position. For example: 9678 79** will map all numbers from 9678 7900 to 9678 7999.
You may have multiple entries with the same name but different numbers. You are then given a choice of barring this user by entering the ‘D’ option. If you press ENTER for this option, the user will always be answered as long at S0 is not 0 and DTR is on.
