S-Registers
Your CheetahModem has S-registers that affect various operating
characteristics. The registers let you obtain information about the
CheetahModem, and let you test the CheetahModem. Each S-Register has a
factory-set value, which you can read or change to fit your particular
requirements.
Reading An S Register Value
1.
To read the current value of an S-Register, type:
ATSr?[Enter]
where r is an S-Register number.
The CheetahModem responds with decimal value of the S-Register, in
three-digit format, followed by
OK
.
2.
To read values from more than one S-Register, type:
ATSr?Sr?[Enter]
where r specify the different S-Register numbers.
For example, to read the value of Register
S0
(number of rings before
answering) and
S1
(incoming ring count), type:
ATS0?S1?[Enter]
Changing An S Register Value
To change an S-Register value, type
ATSr=n[Enter]
Where r is the S-register number.
n is the value you want to assign to that S-register.
