CHAPTER 6: S-Registers
default setting is two seconds. S8 may be set for
up to 255 seconds.
S8 also sets the time the modem waits before
retrying a call after detecting 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-mSec intervals
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
(six units of 100 mSec each). S9 may be set to a
maximum of 255 (25.5 seconds).
S10
Carrier Loss Disconnect Delay Time
Unit: 100-mSec intervals
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 (seven units of 100 mSec
each). Maximum delay is 25.4 seconds (S10 set
to 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.)
