ATH0<Enter>
(Hang up the modem connection)
AT&K3<Enter>
(Enable bi-directional CTS/RTS hardware
flow control)
Mostly the AT commands can also be entered in the same
command line. For example,
AT&K3H0<Enter>
As shown above, it is not necessary to put spaces between the
commands (there is no space between
AT
,
&K3
, and
H0)
.
The modem usually returns an response at the next line if it
understands the command. The response is usually
OK
or
ERROR
unless the AT command has other extended messages.
Add
&W
at the end of the AT command string to save the changes
to modem’s memory (refer to &W commands for details),
otherwise the changes will get lost when you restart or shut down
the computer. You can also use
Zn
command to load the desired
settings automatically when you power up the modem every time.
Type
AT&F&WZ
if you get lost in the AT command and want to
go back to the factory default settings.
Use
AT&V
command to view the active settings.
Exception
Do not precede following commands with an
AT
prefix or
conclude it by pressing
Enter
.

commands. Once you are finished, you may return to data mode
using the ATO command.
A pause, the length which is set by the Escape Guard Time (S12),
must be used after an escape sequence is issued. This pause
