User's Manual

S4 stores the ASCII value of the line feed character, if your computer does not recognize the default as a
line feed, change the value. A value greater than 127 disables the line feed. When disabled, the line feed
character that precedes or follows a result code is canceled.(Pertains to asynchronous operation only.)
Range: 0 - 127, ASCII decimal.
S5 ASCII Value of Backspace Character
S5 stores the ASCII value of the backspace character. The backspace is used to edit a command line. If your
computer does not recognize the default as a backspace, change the value. (Pertains to asynchronous
operation only.)
Set S5 to any value from 0 to 31 or 127. Do not set it to any value from 32 through 126 because these
values correspond to printable ASCII characters. A value greater than 127 disable the backspace and makes
it impossible to edit a command line.
Range: 0 - 32, ASCII decimal.
S6 Wait Time before Blind Dialing
S6 controls how long the modem waits after it goes off-hook before it dials the first digit of the telephone
number. The modem always pauses for at least 2 seconds, even if S6 is set to less than two seconds.
Range: 2 - 255 seconds.
S7 Wait for Carrier after Dial
S7 controls how long the modem waits for a carrier signal from a remote modem after originating a call or
from the calling modem after going off-hook when answering a call.
S7 also controls how long the modem waits for a one-second continuous dialtone after dialing a number
followed by the W dial modifier. If the modem detects a one-second continuous dialtone within the
specified wait time, it proceeds to dial.
Range: 1 - 255 seconds.
S8 Pause Time for Comma
S8 controls how long the modem pauses when a comma ", " is encountered in a dial string while executing
a dial command.
Range: 0 - 255 seconds.
S9 Carrier Detect Response Time
S9 determines how long a carrier signal must be present for the modem to confirm it. The longer the
response time, the easier it is for the modem to correctly recognize a carrier without mistaking other signals
or transient noise on the line as a carrier.
