Section Four - S Registers
Your modem has 28 registers, designated S0
through S92. Table 4-1 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 character-
istics specified in its non-volatile memory. Refer to
Section 3 for information on how to use the AT com-
mands to manipulate the S registers.
