S5
Default=8;
Holds the ASCII decimal value of Backspace character. A value of 128-
255 disables the Backspace key's delete function.
S6
Default=3;
Sets the number of seconds the modem will wait before dialing if X0 or
X1 is selected. If X2, X3, X4, X5, X6, or X7 is selected, modem will dial as soon as it detects a
dial tone. This S-Register also sets the time-out interval for `W' dial modifier to wait for the dial
tone. Range is 1 to 255 seconds. (See also S41b4.)
S7
Default=60;
Sets the number of seconds the modem waits for a carrier. If the modem
does not detect a carrier within this time, it hangs up and returns the NO CARRIER result code.
S8
Default=2;
Sets the duration of delay generated by comma (,) dial modifier. Also
sets the pause between command re-execution for Repeat (>>) command.
S9
Default=6;
Sets the duration, in tenths of a second, that the remote modem's carrier
signal must be present before recognition. When in non-FSK or half-duplex operation, the
modem ignores the setting of this register.
S10
Default=7;
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 cause that momentarily breaks the connection, and a true disconnection (hanging up) by
the remote modem.
S11
Default=70;
Sets the duration and spacing, in milliseconds, in touch-tone dialing.
Note: The number values of ASCII codes are always given as decimals. If you enter values from
the U-1496 front panel you must convert these values to sedecimal (hex) values.
S12
Reserved.
S13
Bit-map register, default=0
(1)
= 1;

Grant remote digital loopback test request.
&T5

Deny remote digital loopback test request.
*Mn
(0)

Auto-handshake on originate mode in leased line operation.

Auto-handshake on answer mode in leased line operation.
S15
Bit-mapped register, default = 130
Zn
(7,6,5) =0-4;
Profile as active settings after power on.
*Cn
(4,3)
=0;
10-bit character length.
=1;
11-bit character length.
=2;
9-bit character length.
=3;
8-bit character length.
Note: Character length includes start bit, data bits, parity, and stop bit(s).
(2)
=0;
1 stop bit.
