AT COMMAND SET

ATNn&Z Store String in NVRAM
Parameters : 0 to 9
Default : None
This command allows up to 44 characters to be stored in each of the ten NVRAM locations
for later recall.
NOTE: Location zero and location one are the ONLY locations that can be dialled on the
rise of DTR.
Locations may hold Alarm Mode text strings (2,3,4), Passwords (5,6,7,8,), numbers to dial
on the raise of DTR (0,1) and number to dial with the ATDNn command for security
callback after a password match (any location). For example:
LOCATION CONTENTS
0 DTR / n0 Dial Number.
1 Alternate DTR / n1 Dial Number
2 Alarm Mode Connect String / n2 Dial Number
3 DTR Raised String / n3 Dial Number
4 Keyboard Activity Alarm String / n4 Dial Number
5 Password Storage / n5 Dial Number
6 Password Storage / n6 Dial Number
7 Password Storage / n7 Dial Number
8 Password Storage / n8 Dial Number
9 Password String / n9 Dial Number
When a stored number is recalled via the ATDNn command, the command processor
effectively enters ATD, fetches location n and then dials the digits in the order it finds
them.
ATO On-line, ORIGINATE and Retrain
Parameters : 0
Default : 0
If the modem is already online, this command causes the modem to return to the Data
Transfer State. If the modem is not online, the modem will attempt to originate a call (go
off hook and wait for answer tone). The modem ignores all commands in a command line
following the Originate command.
ATO0 - Return to On-line State or originate a call.
