(PSTN), two-wire leased line originate or answer, and four-wire leased line
originate or answer.

DIALING OPTIONS

The following LCDs are used to configure dialing options or to dial manually.
TONE/PULSE
Use the Æ and Enter buttons to select between DTMF tone dialing and pulse
dialing. Same as the T and P commands.
BLIND/SMART DIAL OPTIONS
Use the Æ and Enter buttons to select blind dialing, in which the modem sends
the OK, CONNECT, RING, NO CARRIER, ERROR and NO ANSWER messages
to the computer and does not look for a dial tone or busy signal, or smart dialing,
in which the modem sends all messages to the computer, including NO
DIALTONE and BUSY. Same as the X0 and X4 commands.
DIAL NUMBER
Use the front panel buttons to enter a phone number and dial it. To scroll through
a list of digits and characters, press the ↑ Å and ↓ buttons. To go to the next
position, press the Æ button. To back up or to exit without dialing, press the Æ
button several times. To dial the number, press the Enter button. Same as the D
command.
DTR DIALING
Use the Æ and Enter buttons to enable or disable DTR dialing. DTR dialing is
popular in synchronous applications. In DTR dialing, the modem automatically
dials the number stored in memory location 0 when it detects a high DTR (Data
Terminal Ready) signal on the RS-232 interface. The DTR signal must remain
high for the duration of the call. To store the DTR dialing number, use the &Z0=
command or the ENTER PHONE #0 menu option.
Note: Plug and Play does not function if DTR dialing is enabled. DTR is used
during Plug and Play, and DTR dialing interferes with it.
