Sets the durati on, in tenths of a second, of the extra
3000/600 Hz answer tones sent during V.32 hand -
shaking. This gives V.32 modems additional time to
connect in V.32 mode before timing out.
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.
