80
Bit 5-7 Reserved
11.26 S29 - Flash Dial Modifier Time
S29 sets the length of time, in units of 10 ms, that the modem will go on-hook when it encounters
the flash (!) dial modifier in the dial string. The time can be limited as it is a country dependent
parameter.
Range: 0-255 10 ms intervals
Default: 70 (700 ms)
11.27 S30 - Disconnect Inactivity Timer
S30 sets the length of time, in tens of seconds, that the modem will stay online before disconnecting
when no data is sent or received. In error-correction mode, any data transmitted or received will
reset the timer. In other modes, any data transmitted will reset the timer. The timer is inoperative in
synchronous mode.
Range: 0-255 tens of seconds (0-2550 seconds)
Default: 0 (disabled)
11.28 S31 - Bit Mapped Options Status
S31 indicates bit mapped options status.
Default: 192 (C0h) (11000000b)
Bit 0 Single line connect message enable/disable (\Vn)
0 = Messages controlled by S95, Wn and Vn (\V0) (Default)
1 = Single line connect message (\V1)
Bit 1 Reserved (0)
Bits 2-3 Error correction progress messages (Wn)
0 = DTE speed only (W0) (Default)
1 = Full reporting (W1)
2 = DCE (line) speed only (W2)
Bits 4-5 Caller ID (#CID)
0 = Caller ID disabled (#CID=0) (Default)
1 = Short (formatted) Caller ID enabled (#CID=1)
2 = Long (unformatted) Caller ID enabled (#CID=2)
Bits 6-7 Reserved (Default = 11b)
11.29 S36 - LAPM Failure Control
Default: 7 (00000111b)
Bits 0-2 This value indicates what should happen upon a LAPM failure. These fallback
options are initiated immediately upon connection if S48=128. If an invalid number
is entered, the number is accepted into the register, but S36 will act as if the default
value has been entered.
