S8 determines the length of the pause caused by a comma in a dialing command. The default setting is two
seconds for the North American model, and four seconds for the International and U.K. models. S8
may
be set for up to 255 seconds. S8
also defines the length of time the modem waits before retrying a call after
it detects a busy signal. Some computer systems need more than two seconds to reset, in which case you
should increase the value of S8.
S9 Carrier Detect Response Time
Unit: 100 ms
Range: 1–255
Default: 6
S9 determines 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 setti ng is 600 milliseconds (six units of
100 ms each). S9
may be set for up to 25.5 seconds.
S10 Carrier Loss Disconnect Delay Time
Unit: 100 ms
Range: 1–254, 255
Default: 7
S10
defines the length of time after a loss of carrier signal before the modem disconnects. The default
setting is 700 ms (seven units of 100 ms each). Maximum delay is 25.4 seconds (decimal 254). Settin g the
S10
value to 255 causes the modem not to disconnect with loss of carrier.
S11 Tone Dialing Spacing and Duration
Unit: 1 ms
Range: 1–255 (USA) or 80–255 (Canada, U.K., International)
Default: 70 (USA) or 80 (Canada, U.K., International)
S11 sets the speed of tone dialing (spacing and tone duration times). The default value is 70 units for
domestic models and 80 units for Canadian and International models, where each unit is one ms. In other
words, for domestic modems, each tone is sustained for 70 ms followed by a 70 ms p ause. The minimum
S11
value allowed by most telephone systems is 50 ms (50 units). Very few telephone systems can handle
anything faster than that. The maximum S11 value is 255 ms (255 units).
S13 Remote Configuration Escape Character
Unit: Decimal
Range: 0–127
Default: 37 (%)
S13 defines the remote configuration escape character by its decimal ASCII code. The S13
default is the
percent character (decimal 37). When you enter the S13-defined character three consecutive times from a
remote site, your modem responds with its remote configuration procedure. A val ue of 0 disables remote
configuration.
S17 Changing Break Time
Unit: 10 ms
Range: 1–255
Default: 25 (250 ms)
S17 defines the break time (space) the modem sends the DTE when it receives a break signal from a remote
modem. Break duration is adjustable in 10 millisecond increments. The default is set to 25, for a 250
millisecond break.
