3.2.3.3 P - Set Pulse Dial Default
This command forces pulse dialing until the next T dial modifier or T command is
received. Sets S14 bit 5.
As soon as a dial command is executed which explicitly specifies the dialing mode for
that particular call (e.g., ATDT..), this command is overridden so that all future dialing will
be tone dialed. (See T command.) This command may not be permitted in some
countries.
3.2.3.4 A - Answer
The modem will go off-hook and will attempt to answer an incoming call if correct
conditions are met. Upon successful completion of answer handshake, the modem will
go on-line in answer mode. This command may be affected by the state of Line Current
Sense, if enabled. (Most countries do not require Line Current Sense.) Operation is also
dependent upon +FCLASS command and country-specific requirements. If +FCLASS=0
is selected, the modem will enter the connect state after exchanging carrier with the
remote modem. If no carrier is detected within a period specified in register S7, the
modem will hang up. Any character entered during the connect sequence will abort the
connection attempt. If +FCLASS=1.0 is selected, the modem will go off-hook in V.21
answer mode. It will generate the V.21 2100 Hz answer tone for 3 ± 0.5 seconds.
Following a delay of 70 ms, it will proceed as if the +FTH=3 command were issued. At
any stage up to (but excluding) the +FTH=3 command state, any character will abort the
communication. (See the description of the +FTH command for details.)
3.2.3.5 H - Disconnect (Hang-Up)
This command initiates a hang up sequence. This command may not be available for
some countries due to PTT restrictions.
Syntax
H[<value>]
Defined Values
<value> Decimal number corresponding to the selected option.
0 The modem will release the line if the modem is currently on-line.
1 If on-hook, the modem will go off-hook and remain in command mode.
Result Codes
OK <value> = 0 or 1.
ERROR Otherwise.
3.2.3.6 O - Return to On-Line Data Mode
This command specifies that the modem will enter the on-line data mode from the
on-line command mode with or without a retrain. If in the off-line command mode when
this command is entered, the modem reports ERROR.
Syntax
O[<value>]
Defined Values
<value> Decimal number corresponding to the selected option.
0 Enters on-line data mode from the on-line command mode without a retrain.
Handling is determined by the Call Establishment task. Generally, if a connection
exists, this command connects the DTE back to the remote modem after an
