S8 Pause Time For Comma
n 1 – 254 seconds

2 2 seconds
The S8 register sets the number of seconds the modem will pause during a pause created
by a "," (comma) in the dialing sequence.
The effective time will range from (n-1) to n seconds.
S9 Carrier Detect Response Time
n 1 – 254 in 100 ms unit
 6 600 ms
The S9 register sets how long a carrier signal must exist before the modem issues a
carrier detect response.
Note: Carrier detection while the modem is in the on-line state is governed by the times
specified by S9 and S10. The DCD is the carrier detect indicator. If the carrier signal goes
off, DCD goes off within 20 ms. If the carrier returns, CD turns on within 20 ms after the
carrier has been on continuously for the time specified by S9. If CD is off for the time
specified by S10, then carrier is lost and the modem hangs up. If S10 is set to 255, the
modem will not hang up.
S10 Lost Carrier Hang Up Delay
n 0 – 254 in 100ms unit
 14 1.4 second
255 Carrier detect status ignored, no hang up
The S10 register sets (in 10ths of a second) the delay time between loss of carrier and the
modem hanging up. After the S10 delay time, the modem hangs up and returns to
Command State and the modem sends the NO CARRIER response.
