S30 - Inactivity Timeout

Description
To minimize phone line charges, the modem enters the hang-up process whenever both the DTE and the DCE are inactive for a time greater than the value contained in this register, in 10s of seconds. The factory default value of 0 disables this function. This register is ignored in leased-line operation.
