H n
On-Hook/Off-Hook{xe "On-Hook/Off-Hook command"}{xe "AT
commands:H"}{xe "hanging up"}
n = 0 or 1
Default: 0
Use the H command to make the modem hang up (go on-hook) or simulate the action
of picking up a telephone handset (go off-hook).
H0 (or H) hangs up the modem
H1 brings the line off-hook, just as if you had picked up the telephone handset.
It is not necessary to use the H1 command to bring the line off-hook when using the
D command. The modem automatically goes off-hook when you press E
end of the dial command.
Dial Modifier Commands{xe "dialing:modifiers"}
The dial string can include the digits 0 through 9, the pound sign (#), the asterisk
(*), and the letters A, B, C, or D. The latter are used by some {xe "PBX phone
systems"}PBXs; the exact function will depend on the PBX manufacturer's feature
set and implementation. There are also several command characters, called "dial
modifiers," that can be included within a dialing command after the letter D.
Their functions include pulse or tone dialing, pauses in the dial sequence, automatic
redials if a number is busy, and reverting to command mode or switching to answer
mode after dialing.
L
Redial Last Number{ XE "redial last number" }{ XE "AT commands:L" }
Default: none
You can redial the last number dialed by entering L immediately following the dial
command (ATD). This command is handy if you encounter a busy signal and want to
try the call again.
P, T
Pulse or Tone Dialing{xe "AT commands:T"}{xe "AT commands:P"}{xe
"Tone-Dial command"}{xe "Pulse-Dial command"}
Default: T
The MT5634HD8's modems can dial numbers by using pulse dialing, tone dialing, or
a combination of both methods. Pulse dialing, used by rotary-dial telephones, uses
the timed opening and closing of a relay to encode the numbers. Tone dialing, used
by push-button (touch-tone) telephones, uses dual tone multifrequency ({xe "DTMF
(dual tone multifrequency):dialing"}DTMF) dialing.
P selects pulse dialing.
T selects tone dialing.
Insert P or T in the dialing command just before the digits you want to pulse- or tone-
dial. If neither pulse nor tone dialing is specified in the dial command, the modem
uses whatever method was used last.
Note: When your modem is first turned on or reset, it uses the tone dialing method,
(which is the default), even if you do not include T in your dial command.
