Converting Decimal Values to Bits
Convert decimal values to bits by finding the largest decimal equivalent that is less than the decimal
value. Subtract the decimal equivalent and mark the equivalent bit "1." Continue until the decimal
value is zero. See the example below.
113
113 - 64 = 49
01
49 -32 = 17
011
17 -16 = 1
0111
1 -1 = 0
01110001
Setting Bit-Mapped S-Registers
You can set bit-mapped S-Registers using either bits or decimal values. While it may be simpler for
you to set the bits individually, your modem displays the S -Register settings in decimal form.
Using Bits
Turning individual bits on and off is the more direct way to set bit -mapped S-Registers. To do this,
specify the S-Register that you want to set and then indicate which bits you want to turn on (1) or off
(0).
Example:
ATS13.0=1.4=1.5=1, turns bits 0, 4, and 5 on for S -Register 13.
Using Decimal Values
An alternative way to set bit-mapped S-Registers is by adding the decimal values of the bits and
entering the total.
This example, ATS13=49, sets the same value as the one in Using Bits above.

Register
Default
Function
S0
0
Sets the number of rings on which to answer in Auto Answer
mode. S0=0 disables Auto Answer. S0=1 enables Auto Answer and the Courier
Lite 56K Business Modem answers on the first ring.
S1
0
Counts and stores the number of rings from an incoming call.
S2
43
Stores the ASCII decimal code for the escape code character. Default character
is “+”. A value of 128-255 disables the escape code.
