Register Default Function
Setting S28 to zero eliminates the extra
tones, resulting in a faster connect time if,
for example, the modem is set to use V.21
modulation (300 bps) or V.23 modulation
(1200 bps).
S29 20 Sets the duration, in tenths of a second, of
the answer tones sent during V.21 hand-
shaking. Default = 20 (2 seconds). This
gives V.21 modems additional time to
connect in V.21 mode before timing out.
S30 − S31 0 Reserved.
S32 9 Sets the function for the voice/data
switch. This is not a bit-mapped register.
Select the value for the desired function,
for example, ATS32=6.
