MODEM 32144
This command would change the
value of register S7 to 30. If you
enter just =5, the autodialer will
change the value of the last register
used to 5. More information on S
registers is included later in this
chapter.
S?—READ S REGISTER. This
command instructs the autodialer
to read the contents of the
specified S register. The syntax is
Sr?, where r specifies the register to
be read. For example, S7? reads the
value of register S7. The value is
displayed on the computer or
terminal monitor. If you enter ? by
itself, the autodialer will display the
value of the last register used; if = is
entered by itself, the autodialer will
display the number of the last
register used (e.g., S2). For
information on how to interpret S
register values, see
Table 5-3 .
T—TONE DIALING. This
command causes a telephone
number in the dial command
string to be dialed using tone
signals. (See the P command
above for additional information.)
W—WAIT FOR DIAL TONE.
The W command (or colon) is
used in a dial string to instruct the
modem to wait for a dial tone
before proceeding. The wait time
(30 seconds by default) can be
adjusted by changing the value in
register S7. If no dial tone is
detected within the specified time,
the modem will hang up and give a
NO DIALTONE result code (if this
result code is enabled by the X
command).
Z—RECALL STORED USER
PROFILE. The Z command resets
the modem and recalls a profile of
the modem configuration settings
previously saved using the &W
command. The profile is
designated as profile 0 or profile 1
when it is saved using the &W
command.
,—PAUSE. A comma causes the
modem to pause for 2 seconds (or
time specified in register S8)
before processing the next
character in a dial string or
command. This command is used
to place an outside call through a
PBX switchboard, where 9 has to
be dialed to gain outside access—
the pause allows time for the dial
tone to occur before the modem
dials the number.

Similarly, a comma may be used
to cause the modem to wait for a
second dial tone before beginning
to dial a telephone number.
Multiple commas may be used to
increase the pause time.
;—FORCED COMMAND STATE.
A semicolon placed at the end of a
dial command causes the modem
to return to the command state
after dialing without disconnecting.
The following examples illustrate
how the ; command is used:
