S-Register 11—DTMF Tone Duration
S-Register 11 defines the duration/spacing of tones (in milliseconds) in Dual Tone
Multifrequency (DTMF) dialing. This register has no meaning unless the Tone
Length option under the DIALING OPT’S is set to S11. Refer to Appendix C,
Country-Specific Information, for the ranges supported by each country.
S-Register 12—Escape Code Guard Time
This S-Register sets the interval that must be present on either side of the escape
code (+++) in order for the modem to recognize the escape command and enter
command mode. This prevents the +++ characters from putting the modem in
command mode if they are contained in data. The value of S-Register 12 is
multiplied by 0.02 to determine the number of seconds. For example, the value of the
factory default 50 is one second.
If S-Register 12 is set to 0, the speed at which you enter the escape sequence is not a
factor.
S-Register 18—Test Timer
This S-Register determines the duration, in seconds, of loopback tests.
With S-Register 18 set to 0, the timer is not operational and tests must be terminated
manually. NOTE: S-Register 18’s function is valid only when loopback tests are
issued using the AT&T command. S-Register 18 cannot be used to automatically
terminate loopback tests if the test is initiated from the front panel.
