-Register Option Description
S0 Auto-Answer on Ring Number
S0=0 Disable
S0=n Answer on Ring n; n=0 to 255
S1 Ring Count
S1=n Counts the number of rings in an incoming call. If the modem is
configured to auto-answer (S0 set to a non-zero option), when S1=S0, the
modem answers the call.
S2 Select Escape Character
S2=n Specifies ASCII character for Escape; n=0 to 255. Default = 43 (+)
S3 Select Carriage-Return Character
S3=n Specifies ASCII character for Carriage-Return; n=0 to 127. Default
= 13 (CR)
S4 Select Line-Feed Character
S4=n Specifies ASCII character for Line-Feed; n=0 to 127. Default = 10
(LF)
S5 Select Backspace Character
S5=n Specifies ASCII Character for Backspace; n=0 to 127. Default = 8
(BS)
S6 Blind Dial
S6=n Before dialing, the modem goes off-hook and waits n seconds; n=0 to
255. Note: When the ATX2 or ATX4 option is in effect, the S6 value is
disregarded.Default = 2
S7 Call Time-out
S7=n Pause for n seconds; n=0 to 255; before dialing. Default = 60
S8 Pause Delay
S8=n Pause for n seconds; n=0 to 255; for dial modifier in a dial
string. Default = 2
S10 DCD Loss Disconnect
S10=n Disconnect after n seconds; n=0 to 255 in 0.1 second increments;
after DCD signal is de-asserted. Default = 14
S11 Tone Length
S11=n Specifies duration, in 0.001 second increments, of DTMF tone when
it is generated; n=60 to 255. Default =72
S12 Escape Code Guard Time
S12=n Specifies the interval, in 0.02-second increments, that must be
present on either side of the escape code (+++) for the modem to
recognize the escape command and enter command mode. If S12=0, the
speed at which you enter the escape sequence is not a factor. Default =
50
S18 Test Timer
S18=n Specifies test execution duration; n=0 to 255. Default = 0
