AT command set
The modem will respond to the commands detailed below. Parameters applicable to each
command are listed with the command description.
&Bn Ð RTS Dial Option
This command stores the current profile and enables or disables the dialing with active
RTS from DTE. The modem will dial the address stored with AT&Z0=.....
&B0 Disable dial with active RTS signal.
&B1 Enable dial with active RTS signal.
Observe that this will take the modem to RTS-mode and an active RTS from DTE will be interpreted
as a dial command. There are three possibilities to leave RTS-mode.
Number one is to use the (&B0) command with RTS inactivated.
Number two is to use the escape sequence when the modem is connected and then disable the dial
with RTS (&B0).
Another possibility is to remove the D-sub or the RS-232 screw block (inactivate RTS) and repower
the modem and then use switch S4:8 which works as a reset switch and will disable the dial with
active RTS-signal (&B0).
The modem will be reset on a ON to OFF to ON sequence on switch S4:8.
Switch S4:8 can only be used when the modem is disconnected from the line.
&Cn Ð DCD Option
This command controls the DCD signal.
&C0 DCD active at all times.
&C1 DCD active when a connection is established (default).
