Section Seven - S Register Summary

Table 7-1 shows the registers, their functions, and their default

values. Some registers can have their values changed by commands. If

you use a command to change a register value, the command remains in

effect until you turn off or reset your modem. Your modem then reverts to

the operating characteristics specified in its non-volatile memory. Refer to

Section 6 for information on how to use the AT commands to manipulate

the S registers.

Note: The default value and range of some S-registers lists below

could be vary with countrys.
