\Bn - Transmit Break to Remote
In non-error-correction mode, the modem will transmit a break signal to the remote modem with a length in
multiples of 100 ms according to parameter specified. If a number in excess of 9 is entered, 9 is used.
\Fn - Set Answer or Originate Mode
In dial operation the answering modem typically assumes answer responsibility and the calling modem
assumes originate responsibility. In leased line operation where there is no implied calling or answering
modem, the relationship must be established with this command. Please note that setting the modem to
answer mode is not the same as setting the modem to auto-answer mode. S register 0 must still be set for
auto-answer dial operation.
\F0
Sets modem to answer mode.
\F1
Sets modem to originate mode.
\Gn - Modem to Modem Flow Control (XON/XOFF) (1442 ONLY)
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. 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.
\G0
Disables modem to modem flow control. (Default)
\G1
Enables modem to modem XON/XOFF flow control.
\Hn - Auto-Connect
In many cases where the dumb mode of operation is required, it is necessary for the modem to be configured
so that it constantly attempts to go off hook and connect as configured. This is necessary for leased line
operation or for operation with an external manual dialer. This command allows that to occur.
\H0
Normal dial/answer operation under AT command control. (Default)
\H1
Modem constantly attempts to go off hook and connect as configured.
\Kn - Break Control
Controls the response of the modem to a break received from the DTE or the remote modem or the \B
command according to the parameter supplied. The response is different in three separate states. The first
state is where the modem receives a break from the DTE when the modem is operating in data transfer
mode:
\K0
Enter on line command mode, no break sent to the remote modem.
\K1
Clear data buffers and send break to remote modem.
\K2
Same as 0.
\K3
Send break to remote modem immediately.
\K4
Same as 0.
\K5
Send break to remote modem in sequence with data. (Default)
The second case is where the modem is in the on-line command state (waiting for AT commands) during a
data connection and the \B is received in order to send a break to the remote modem:
