For example, type:
ATH0<Enter> to hang up the modem connection,
or
AT&K3<Enter> to enable bi-directional CTS/RTS
hardware flow control.
Most of the AT commands can be entered in
“strings” (i.e., on the same command line) without
spaces between the individual commands. For
example:
AT&K3H0<Enter>
As shown above, it is not necessary to put spaces
between the commands. So, there are no spaces
between
AT
,
&K3
, and
H0
.
The modem usually returns a response (or “Result
Code”) at the next line if it understands the
command. The response is usually
OK
or
ERROR
unless the AT command provides other (extended)
messages.
