Section Four - S Registers

Your modem has 41 registers, designated S0 through S95. 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.
