User’s Manual D-3
S-registers
S5 Command line editing character (user defined)
This register sets the character recognized as a backspace and
pertains to asynchronous only. The modem will not recognize the
backspace character if it is set to a value that is greater than 32
ASCII. This character can be used to edit a command line. When
the echo command is enabled, the modem echoes back to the
local DTE the backspace character, an ASCII space character,
and a second backspace character. This means a total of three
characters are transmitted each time the modem processes the
backspace character.
Range: 0-127, ASCII decimal
Default: 8 (backspace)
Units: ASCII
S6 Wait before dialing
This register sets the length of time, in seconds, that the modem
must wait (pause) after going off-hook before dialing the first digit
of the telephone number. The modem always pauses for a
minimum of two seconds, even if the value of S6 is less that two
seconds. The wait for dial tone call progress feature (W dial
modifier in the dial string) will override the value in register S6.
This operation, however, may be affected by some ATX options
according to country/region restrictions. In some countries/regions,
S6 will set dial tone detect time.
Range: 3-255
Default: 3
Units: seconds
S7 Connection completion time-out
This register sets the time, in seconds, that the modem must wait
before hanging up because carrier is not detected. The timer is
started when the modem finishes dialing (originate), or goes off-
hook (answer). In originate mode, the timer is reset upon detection
of an answer tone if allowed by county restriction. The timer also
specifies the wait for silence time for the @ dial modifier in
seconds. S7 is not associated with the W dial modifier.
Range: 1-255
Default: 50
Units: seconds
