6000768 - Telepath Voice 56k Faxmodem
S-Register Information
S0 Sets the number of rings on which to answer in auto answer mode. S0=1 means the modem answers on the first ring. S0 = 0 means auto answer is disabled; modem answers on 0 rings, and it does not answer at all.
S1 Counts and stores the number of rings from an incoming call. Default is 1.
S2 Stores the ASCII decimal code for the escape code character. Default character is a plus sign "+". A value from 128-255 disables the escape code. Default is 43.
S3 Stores the ASCII code for the carriage return character. Valid range is 0-127. Default is 13.
S4 Stores the ASCII decimal code for the line feed character. Valid range is 0-127. Default is 10.
S5 Stores the ASCII decimal code for the BACKSPACE character. A value from 128-255 disables the BACKSPACE key's delete function. Default is 8.
S6 Sets the number of seconds the modem waits before dialing. If set to ATX2 or ATX4, the modem ignores this register and dials as soon as it detects a dial tone (fast dials). Default is 2.
S7 Sets the number of seconds the modem waits for a carrier. May be set for much longer duration if, for example, the modem is originating an international connection. Default is 60.
S8 Sets the duration, in seconds, for the pause (,) option in the Dial command. Default is 2.
S9 Sets the required duration, in tenths of a second, of the remote modem's carrier signal before recognition by the TelePath. Default is 6.
S10 Sets the duration, in tenths of a second, that the modem waits after loss of carrier before hanging up. This guard time allows the modem to distinguish between a line hit or other disturbances that momentarily break the connection from a true disconnect by the remote modem. If you set S10 = 255, the modem doesn't hang up when carrier is lost. Drop DTR to force the modem to hang up. Default is 7.
S11 Sets the duration and spacing, in milliseconds, of dialed tones. Default is 70.
S12 Sets the duration, in fiftieths of a second, of the guard time for the escape code sequence (+++).
S13 Bit-mapped register. Select the bit(s) you want on and set S13 to the total of the values in the Value column. For example, ATS13=17 enables bit 0 (value is 1) and bit 4 (value is 16). Default is 0.

Reset non-ARQ mode Transmit buffer from 1.5 Kilobyte (KB) to 128 KB. The 1.5 KB non-ARQ buffer allows data transfer with X and Y modem-type file transfer protocols without using flow control. The 128-byte options allows remote users with slower modems to stop data you're transmitting from scrolling off their screens. When remote users send your computer an XOFF (CTRL+S) and you stop transmitting, the data in transit from your modem's buffer doesn't exceed the size of their screen. |

S18 Test timer for AT&Tn loopback testing. Sets the duration of testing, in seconds, before the modem automatically times out and terminates the test. S18 = 0 disables the timer. Default is 0.
S19 Sets the duration, in minutes, for the inactivity timer. The timer activates when there is no data activity on the phone line hangs; at timeout the modem up. S19 = 0 disables the timer. Default is 0.
S21 Sets the length, in 10 millisecond units, of breaks sent from the modem to the computer; applies to ARQ mode only. Default is 10.
S22 Stores the ASCII decimal code for the XON character. Valid range is 0-127. Default is 17.
S23 Stores the ASCII decimal code for the XOFF character. Valid range is 0-127. Default is 19.
S25 Sets the duration, in hundredths of a second, that DTR must be dropped so the modem doesn't interpret a random glitch as a DTR loss. Default is 5.
S27 Bit-mapped register. Select the bit(s) you want on and set S27 to the total of the values in the Value column. For example, ATS27=17 enables bit 0 (value is 1) and bit 4 (value is 16). Default is 0.
