S-Registers
Certain Command Mode configurations are stored in memory registers
called, S-Registers. The
S
command is used to assign a value to, and to
read the current value of an S-Register. To assign a value to an S-
Register, enter the letter
S
,
followed by the S-Register number and an
equals sign (
=
).
To read an S-Register value, enter the letter
S
followed
by the S-Register number and a question mark (
?
), then hit RETURN. To
verify that the S-Register value was entered correctly, enter for example,
ATS8?
and hit RETURN. You should receive a response of the assigned
value given to that S-Register.
