The
ATX4
command causes the command modem to wait for a
dial tone before
dialing. This command is referred to as the smart
dialing method where as the
ATX3
command is referred
to as
blind dialing. The CONNECT xxxx result codes are activated and
the BUSY
result code is enabled if a busy signal is detected from
the called command modem. The
ATX4
command is the factory
default setting.
The Result Code Set/Call Progress X commands are summa-
rized below.
ATX0
Basic result codes are enabled. Dumb dialing (dial tone
and busy
signal) capability is provided.
ATX1
Extended result codes are enabled. Dumb dialing
capability is
provided.
ATX2
Wait for dial tone before dialing is enabled. Extended
result codes
are enabled. Busy signal is not detected.
ATX3
Blind dialing is enabled along with extended result
codes. Busy
result code is enabled if the busy signal is
detected.
ATX4
Smart dialing is enabled with extended result codes.Smart dialing
provides dial tone and busy signal detec
tion.
ATX4
is the factory default setting.
Select Stored
The Select Stored Profile on Power Up
&Y
command determines
Profile on Power
which stored
profile is established on power up or reset of the
Up
command modem. The
&Y0
command selects stored
profile 0
and
&Y1
selects stored profile 1 on power up or reset. The profile
&Y0-1
is stored
using the
&W
command.
&Y0
is the factory default
setting.
Recall
The
Z
command causes the command modem to retreive the
Stored
stored configuration from non-volatile memory (NVRAM) and
Profiles
store it in the active
configuration area. The command mode
buffer is cleared after the
Z
command is executed. The
ATZ0
Z0-1
command loads profile 0 into the active configuration area and
ATZ1
command loads profile 1. The active profiles are stored
using the
&W
command and viewed using the
&V
command
which are explained earlier in this section.
Store Telephone
The Store Telephone Number
&Z
command causes the com-
Number
mand modem to store
up to four strings of telephone numbers
into NVRAM for later recall by the Dial Stored Number
ATDSx
&Z0-3=x
command. The format for this command is
&Z
and up to a 36
character telephone number and/or dialing
modifiers which are
stored at location 0. If the command format is
&Z=
(=is a
delimiter)
with no number preceding the delimiter, this telephone
number is also stored at location 0. If the format
of this command
is
&Zx=
where the number preceding the delimiter is between 0
and 3, the
telephone number and/or dialing modifiers are stored
at the loaction specified by the number preceding the
delimiter.The following characters are allowed to be stored: 0 through 9,
A through D,
T P R W # * , ! ; along with the delimiter (=).
Dial Digits/
Digits 0 through 9 and characters A through D, # and * are valid
Characters
dial
characters. Characters A through D, # and * represent
specific tone pairs and therefore, can be used
only when tone
0 to 9, A to D,
dialing.
# and *
Wait for Quiet
The Wait for Quiet Answer
@
command causes the command
Answer
modem to look for
rings followed by 5 seconds of silence before
processing the next symbol in the dial command. This command
@
is used for accessing a system that does not provide a dial tone.S-Register S7
determines the maximum wait time. If Quiet
Answer is detected, the dial modifiers following the command are
executed. If busy is detected, the command modem returns a
BUSY result code and
goes to the hang-up process, aborting
further execution of commands.
Flash On Hook
The Flash On Hook
!
command causes the command modem
to to go on hook for
0.75 second. Some switch-board systems
react to a momentary on hook state. An exclamation point
inserted in the dialing command causes the command to flash
on hook for three-quarters of a second, just as if
you had
depressed the disconnect button (on the handset cradle)
momentarily.
Automatic
You can cause the command modem to pause during the
Pauses in
dialing sequence by entering a comma character where the
Dialing
pause is desired. This pause will last two seconds. If a longer
