S-REGISTER SUMMARY
USAGE
The default values are those users typically require. Change the
settings of an S-Register with the ATS
r=n command, where r is
the register and n is a decimal value from 0-255:
ATS13=8
The modem does not perform a value-range check. Some
values you select may not work with some equipment, and
you'll have to readjust the settings.
Some registers (S13, S14, S15, S16, S27, S34) are bit-mapped (bits
0-7). For example, turning on bit 0 of S13 causes the modem to
reset each time the computer or terminal drops its Data
Terminal Ready (DTR) signal. Turning on bit 3 of S13 causes
the modem, on receipt of DTR, to auto dial the number stored at
position 0 in NVRAM.
To turn on one or more bits in any bit-mapped register, use the
total of the values shown below. For example, S13=9 turns on
bits 0 (value of 1) and 3 (value of 8).
Alternatively, identify the bits to be turned on with the
following format: S
r.b=1, where r is the register and .b is the bit.
This format does not require knowledge of the bit's value.
S13.0=1 .3=1 is the equivalent of S13=9, above. To turn off a bit
function, set it to zero: S13.0=0.
To display the contents of a register, use ATS r? as in this
example:
ATS19?
