5-2 CHAPTER 5: WORKING WITH MEMORY
Example: Sending ATI5 will display NVRAM settings on your screen.
To see a complete listing of the permanent settings stored in Flas h
memory see Appendix C, Flow Control Templates.
Working with RAM
and NVRAM You can change any setting just for the current session. For example
setting your Business Modem to AT&N8 will only allow a connection to a
remote devices at a rate of 14400 bps until the modem is reset. Once the
modem is reset, the default variable connection rate will be
re-established.
If you want the new setting to be a default, write it to NVRAM at the
same time. From the example above, you would send AT&N8&W to the
modem. The new default setting for your Business Modem will only allow
a 14400 bps connection to a remote device.
To restore NVRAM factory defaults use the AT&Fn command. See
Appendix B, Alphabetic Command Summary, for more information on
setting &Fn.
Saving a Phone Number to NVRAM
CAUTION: Do not include modem commands in AT&Zn=s.
Example: To store the phone number 555-6789 at position 2, type
AT&Z2=555-6789. If you want to dial the phone number you saved, type
ATDS2.
For your modem to Command
Write the phone number (s) to a position (n) in memory. You can
store up to 10 phone numbers of up to 40 characters each in
positions 0-9.
AT&Zn=s
Display the number stored in the last-dialed number buffer ATDL?
Display the phone number stored in NVRAM at position n, where
n = 0*9. AT&Zn?
