Status Registers & Result Codes  23

Sets the length of time, in tenths of a second, that the modem waits before hanging up
after a loss of carrier. This allows for a temporary carrier loss without causing the local
modem to disconnect.

S11 - DTMF Tone Duration

Sets the duration of tones in DTMF dialing. This value has no effect on pulse dialing.

S12 - Escape Prompt Delay (EPD)

Defines the maximum period, in fiftieths of a second, allowed between receipt of the
last character of the three escape character sequence from the DTE and sending of the
OK result code to the DTE. If any characters are detected during this time, the OK will
not be sent. Note that sending of the OK result code does not affect entry into command
mode.

S18 - Test Timer

Sets the length of time, in seconds, that the modem conducts a test (commanded by
&Tn) before returning to the command mode. If this register value is zero, the test will
not automatically terminate; the test must be terminated from the command mode by
issuing an &T0 or H command. When S18 is non-zero, the modem returns the OK
message upon test termination.

S25 - Delay To DTR

Sets the length of time that the modem will ignore DTR for taking the action specified
by &Dn. Its unit is one hundredth of a second.

S26 - RTS to CTS Delay

Sets the time delay, in hundredths of a second, before the modem turns CTS ON after
detecting an OFF-to-ON transition on RTS when &R0 is commanded.

S30 - Disconnect Inactivity Timer

Sets the length of time, in minutes, 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. Set S30=0 to disable the timer.
