S9Carrier Detect Response Time
Unit: 100 mSec.
Range: 1-255
Default: 6
Description: S9 sets the time delay between when the modem first detects a valid incoming
carrier signal and when the modem turns on its Carrier Detect circuit. The default
setting is 600 milliseconds, or six units of 100 mSec each (Decimal 6). S9 may be set
for up to 25.5 seconds.
S10Carrier Loss Disconnect Delay Time
Unit: 100 mSec.
Range: 0-255
Default: 7
Description: S10 sets the time a carrier signal must be lost before the modem disconnects. The
default setting is 700 mSec, or seven units (Decimal 7) of 100 mSec. Maximum delay
is 25.4 seconds (Decimal 254). Setting the S10 value to 255 causes the modem to
not disconnect with loss of carrier. (This S-Register applies at speeds of 2400 bps
and less.)
S11Tone Dialing: Tone Spacing and Duration
Unit: 1 mSec.
Range: 1-255, 80-255*
Default: 70, 80*
Description: S11 sets the speed of tone dialing (spacing and tone duration times). The default
value is 70 units (Decimal 7) or 80 units, where each unit is one mSec, meaning that
each tone is on for 70 mSec with a 70 mSec pause between each.
The minimum S11 value allowed by most telephone systems is 50 mSec (50 units).
Very few telephone systems can handle anything faster than that. The maximum S11
value is 255 mSec (255 units).
