Command: &Fn Restore Factory Configuration (Profile)
Values: n = 0
Default: None
Description: The modem loads the factory default configuration (profile). The factory defaults are
identified for each command and in the S-Register descriptions. A configuration (profile)
consists of a subset of S-Registers.
&F0
&F1
Command: &Gn Select Guard Tone
Values: n = 0, 1, or 2
Default: 0
Description: This command causes the modem to generate the guard tone selected by this command
(DPSK modulation modes only). This command may not be permitted in some countries.
&G0 Disables guard tone.
&G1 Disables guard tone.
&G2 Set guard tone to 1800 Hz.
Command: &Kn Flow Control
Values: n = 0, 3, 4, 5
Defaults: 3
Description: This command defines the DTE/DCE (terminal/modem) flow control mechanism. The
parameter value, if valid, is written to S39 bits 0, 1, and 2.
&K0
&K3
&K4
&K5
Command: &Pn Select Pulse Dial Make/Break Ratio
Values: n = 0, 1, 2, 3
Default: Country-Dependent
Description: This command determines the make/break ratio used during pulse dialing. It is only
effective if the appropriate bit to enable this command is set through the country
profile. The default is country-dependent. The parameter value, if valid, is written to
S28 bits 3 and 4.
&P0
&P1
&P2
&P3
Command: &R RTS/CTS Option
Values: 0, 1
Default: None
Description: This selects how the modem controls CTS. The CTS operation is modified if hardware flow
control is selected (see &K command). The parameter value, if valid, is written to S21 bit 2.
&R0 In sync mode, CTS tracks the state of RTS; the RTS-to-CTS delay is defined by S26.
&R1 In sync mode, CTS is always ON (RTS transitions are ignored), tracks the state of
Command: &Sn DSR Override (&S has no functionality in V.22bis)
Values: n = 0, 1
Default: 0
Description: Selects how the modem will control DSR. The parameter value, if valid, is written to
S21 bit 6.
&S0
&S1

Restore factory configuration 0.
Restore factory configuration 1. (Not available in V.22bis).
Disables flow control.
Enables RTS/ CTS flow control.
Enables XON/XOFF flow control.
Enables transparent XON/XOFF flow control.
Selects 39%-61% make/break ratio at 10 pulses per second. (Default in V.22bis))
Selects 33%-67% make/break ratio at 10 pulses per second.
Selects 39%-61% make/break ratio at 20 pulses per second.
Selects 33%-67% make/break ratio at 20 pulses per second.
In async mode, CTS is normally ON and will turn OFF only if required by flow control.
RTS; In async mode, CTS is normally ON and will turn OFF only if required by flow
control.
DSR is always high (ON).
DSR goes high (ON) only during a connection.
