Bits 2-3 Speaker control (Mn)

0 = Disabled (M0)

1 = Off on carrier (M1) (Default.)

2 = Always on (M2)

3 = On during handshake (M3)

Bits 4-6 Limit result codes (Xn)

0 = X0

4 = X1

5 = X2

6 = X3

7 = X4 (Default.)

Bit 7 Reserved

11.20 S23 - General Bit Mapped Options Status

S23 indicates the status of command options.

Default: 0

Bits 0-6 Not used

Bits 6-7 Guard tone (&Gn)

0 = None (&G0) (Default.)

1 = None (&G1)

2 = 1800 Hz (&G2)

11.21 S24 - Sleep Inactivity Timer

S24 sets the length of time, in seconds, that the modem will operate in normal mode with no

detected telephone line or DTE line activity before entering low-power sleep mode. The timer is

reset upon any DTE line or telephone line activity. If the S24 value is zero, neither DTE line nor

telephone inactivity will cause the modem to enter the sleep mode.

Range: 0-255 seconds

Default: 0

11.22 S25 - Delay To DTR off

S25 sets the length of time that the modem will ignore DTR for taking the action specified by &Dn.

Its units are seconds for synchronous modes and one hundredths of a second for other modes.

Range: 0-255 (1 second for synchronous modes 1; 0.01 second otherwise)

Default: 5

11.23 S26 - RTS to CTS Delay

S26 sets the time delay, in hundredths of a second, before the modem turns CTS ON after detecting

an OFF-to-ON transition on RTS when &R0 is commanded. Pertains to synchronous operation only.
