Register Default Function S10 (continued) Although it is not recommended to connect to a line with call waiting, the S10 register can be adjusted upward to prevent the modem from misinterpreting the second call signal as a remote disconnect.
Register Default Function S14 0 Reserved S15 0 Bit-mapped register setup. To set the register, see instructions for S13. Bit Value Result 0 1 Disable ARQ/MNP for V.22. 1 2 Disable ARQ/MNP for .22bis. 2 4 Disable ARQ/MNP V.32 / V.32bis / V.32terbo. 3 8 Disable MNP handshake.
Register Default Function S25 5 Sets the duration (in hundredths of a second) that DTR must be dropped in order to be interpreted as a DTR loss. Allows the modem to differentiate between a random glitch and a true DTR loss. In most cases, the default value can be used.
Register Default Function S29 20 Sets the duration (in tenths of a second) of the V.21 answer mode fallback timer. S30 0 Reserved. S31 128 Reserved. S32 2 Bit mapped register setup for 28.8 modems only. To set the register, see the instructions for S13.
Register Default Function S38 0 Sets an optional delay (in seconds) before a forced hang-up and clearing of the Transmit buffer when DTR drops during an ARQ call. This allows time for a remote modem to acknowledge receipt of all transmitted data before it is disconnected.
