To verify that you entered the value correctly in the above examples,
enter 

and hit RETURN in the first example, 

in the

second, and 

in the third example. You should receive the

response 005 in the first example, 030 in the second example, and 055
in the third example.

When configuring the S-Registers, it is a good practice to include the
verification read-entry in the same command line as the configuration
assignment-entry. In the three preceding examples, enter

The vast majority of installations are similar, with the Series II Modem
being used to dial up a remote installation where the call is automati-
cally answered. Your Series II Modem has a default configuration to dial
another 33,600 bps modem that support error correction, data com-
pression and flow control. If the answering modem is not compatible,
the Modem can match protocols, provided the protocols are industry
standard (i.e., ITU or Bell) and not proprietary. 

The 

command, used in conjunction with specific other AT

commands and S-Registers, can re-configure the Modem to conform to
a specific application. The command 

(or 

) causes the

modem to store its current parameters in its nonvolatile RAM. The
command also sets the modem upon power up, or when it is reset with
an 

command, the modem reads all of its configuration and S-

Register parameters from RAM, and not from the factory settings in
ROM (note that you may recall factory installed defaults by entering

). The 

command changes the configuration para-

meters stored in RAM that you specifically intend to alter. All other
default parameters remain unchanged.

The 

command sets the modem so that it does not store its

parameters in RAM, and on power up or when an 

command is

issued, parameters are read from the factory default settings in ROM.

Before using the 

command, you may want to view the modem's

current operating parameters. Use the

com-

mands to display the current modem configuration.
