Section Four - S Registers
Your modem has 39 registers, designated S0 through
S27, S36-S38, S46, S48-S50, S63, S82, S86, and S98. 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 commands to
manipulate the S registers.
