%Fn – Split-Speed direction select, V.23
Determines which direction (transmit or receive) has the 75bps channel and which has the 1200bps
channel. This command is only valid if the \W1 command has been executed.
%F1 Selects 75Tx/1200Rx. resets S28 bits 1 and 2. (Default.)
%F2 Selects 1200Tx/75Rx. resets S28 bits 1 and resets S28 bit 2.
%F3 Selects 1200Tx/1200Rx. half duplex.

\F – display telephone directory
The modem displays the telephone directory entries which were stored with the &Z command.

&Gn – Select Guard Tone
The modem generates the guard tone selected by this command according to the parameter supplied
(DPSK modulation modes only). The parameter value, if valid, is written to S23 bits 6 and 7.
&G0 Disables guard tone. (Default.)
&G1 Disables guard tone.
&G2 Selects 1800 Hz guard tone.
This command may not be permitted in some countries.
\Gn – Modem-to-Modem Flow Control (XON/XOFF)
In non-error correction mode, the modem enables or disables the generation or recognition of
modem-to-modem XON/XOFF flow control according to the parameter supplied. The parameter
value, if valid, is written to S41 bit 3.
In error correction mode, the setting of modem-to-modem XON/XOFF flow control is ignored.
However, the serial port flow control settings (AT&K) remain active during a reliable link.
Due to the buffering system used in the modem, modem-to-modem flow control is normally disabled.
\G0 Disables modem-to-modem XON/XOFF flow control. (Default.)
\G1 Enables modem-to-modem XON/XOFF flow control.
