The maximum number of seconds the modem should wait, after dialing is completed, for an indication that a modem-to-modem connection has been established. If a connection is not established in this interval, the call is assumed to have failed. This member is equivalent to register S7 in Hayes® compatible modems.
The maximum number of seconds of inactivity allowed after a connection is established. If no data is either transmitted or received for this period of time, the call is automatically terminated. This time-out is used to avoid excessive long-distance charges or online service charges if an application unexpectedly locks up or the user leaves.
