6.4 S Register

The modem uses status registers to control operation.

S-registers can be read and written with the ATS command.

Certain S-registers can only be read, while others can only be set within a limited range

of values.

If a value limit is exceeded, the modem will respond OK, even though the value is not ac-

cepted. Therefore, it is recommended to check the contents of a register, after changes

have been made by use of the ATS<n>? command.
