D[method] [d.d.d.d]
[/ppppp]
or
D[method] [[@]name]
[/ppppp]
Dial a connection to a remote IP and Port using either UDP, TCP, or Telnet.
method =
P — Establish a UDP connection
T — Establish a TCP connection
N — Establish a Telnet connection
d.d.d.d = IP address to establish connection to
name = Domain name to establish connection to
ppppp = IP port to establish connection to
Examples:
ATD — Dial (establish) default connection per S53
ATDPnnn.nnn.nnn.nnn[/ppppp] — Dial (establish) UDP session to the specified IP address/
port.
If the method, IP address, or port is omitted, the values from S53 are used. If a Telnet
connection is requested (N) and the port is not supplied, port 23 will be used instead of the
value from S53.
Several special dialing numbers exist to make it easy to establish a PPP connection with the
device. ATD#19788 or ATDT#19788 will establish a PPP connection (see \APPP on
page 360).
If a domain name is specified, the ‘@’ symbol can be used to explicitly indicate the start of
the name. For example, if “ATDPHONY” is issued, this will be interpreted as dial a UDP
connection to “HONY”. To dial using the default method to host “PHONY”, one would issue
“ATD@PHONY”.
To end the connection, issue the +++ escape sequence or drop the DTR line (if Ignore DTR
S211=0 or &D2).
Note: The source port of the session is the Device Port (set by *DPORT).
&D Query or set Data Terminal Ready (DTR) mode.
AT&D? to query
AT&Dn to set
• n=0 — Devices ignores DTR, same effect as HW DTR always asserted (same as
S211=1); DTD is assumed to be on.
• n=1 — DRT drop causes the device to switch to AT command mode, but does not drop
the connection.
• n=2 — DTR drop causes the connection to drop.
• n=3—DTR drop causes the connection to reinitialize.
If you have a GX Series device with an I/O X-Card installed, you can query or set the main
port on the device or the port on the X-Card by specifying the port number. If no port is
specified, the query or command affects the port your are telnetting to.
AT&D?,[p] to query
AT&Dn,[p] to set
• p=0—Main serial port on the device
• p=1—Serial port on the I/O X-Card
Note: Do not use an equal sign (=) when issuing the command.
