AT Commands
Direct Communication can be used with the Raven to contact other Internet devices
to pass information or other tasks.
TABLE 14. Direct Communication
Command Parameters Details
D[method][d.d.d.d][/ppppp]
or
D[method][@name][/ppppp]
method =
P - Establish a
UDP connection
T - Establish a
TCP connection
N - Establish a
Telnet connec-
tion
d.d.d.d = IP
address to con-
tact
name = domain
name to contact
ppppp = IP port
to contact
Dial a connection to a remote IP and Port using either
UDP, TCP, or Telnet.
Examples:
ATD - Dial (establish) default connection per S53
ATDP192.168.13.31/2332 - Dial (establish) UDP ses-
sion to the specified IP address, 192.168.13.31, at port
2332.
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 or SLIP connection with the modem.
ATD#19788 or ATDT#19788 will establish a PPP con-
nection (see \APPP) and ATDT#7547 will establish a
SLIP connection (see \ASLIP).
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 inter-
preted 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 S110 or *DPORT)
PINGd.d.d.d[,n]
or
PING domain_name[,n]
d.d.d.d = IP
address to con-
tact
n = amount of
data to send
Ping the specified IP address.
Sends a single ping, returns either OK or ERROR
depending on result. Times out in 10 seconds. If n is pro-
vided, it specifies the amount of data to send with the
ping. If n is not provided, the default, 50 bytes is used.
