To determine a value of a bit-mapped register, follow these
steps:
1. Decide which bits in the register you want on or off by
referring to
Table 3
(See also the explanation of the
individual S registers in
The S Registers
section.)
2. Add up the values of all the bits that you want on. (Bits
that are off have a numeric value of zero.)
3. Type the command to change the S register as described
above, entering the new value as a three-digit number; for
example, ATS14 = 074.
To interpret the value of a bit-mapped register, you need to
determine which bit values equal that number when added
together. For example, if S register 14 has a value of 074, bits
1, 3, and 6 must be on, since the values of bit 1 (2), bit 3 (8).
and bit 6 (64) add up to 74. See
Table 3
to find out what
modem functions are controlled by the bits in the register.
