Section Four - S Registers

Your modem has 24 registers, designated S0 through S33. Table 4-1 shows the registers, their func- tions, and their default values. Some registers can have their values changed by commands. If you use a com- mand 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 3 for informationonhowtousetheATcommandstomanipulate the S registers.
