38 Status Registers & Result Codes
S10 - Lost Carrier To Hang Up Delay
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. When register S10 is set to 255, the modem functions as if a
carrier is always present.
The actual interval the modem waits before disconnecting is the value in register S10
minus the value in register S9.
Therefore, the S10 value must be greater than the S9 value or else the modem
disconnects before it recognizes the carrier.
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 units are seconds for synchronous modes and one hundredths of a second for
other modes.
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. Pertains to
synchronous operation only.
S30 - Disconnect Inactivity Timer
Sets the length of time, in tens of seconds, 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. The timer is inoperative in synchronous mode.
