The following is an AT command used to connect to a PPP server by modem. Use this command for old ppp
servers that prompt for a login name (replace username with the correct name) and password (replace
password with the correct password). Note that debug crtscts and defaultroute 192.XXX.XX.XXX are
optional.
moxa@Moxa:~# pppd connect ‘chat -v ““ ATDT5551212 CONNECT ““‘ login: username \
password: password’ /dev/ttyM0 115200 \
debug crtscts modem defaultroute 192.1.1.17
If the PPP server does not prompt for the username and password, the command should be entered as follows
(replace usernamewith the correct username and replace passwordwith the correct password):
moxa@Moxa:~# pppd connect ‘chat -v ““ ATDT5551212 CONNECT ““‘ user username
password password /dev/ttyM0 115200 crtscts modem
The pppd options are described below:
connect
chat etc...
This option gives the command to contact the PPP server. The
chat
program is used to
dial a remote computer. The entire
command is enclosed in single quotes because
pppd expects a one
-word argument for the connect option. The options for chat
are
given below:
-
v
verbose mode; log what we do to syslog
Double quotes
dont wait for a prompt, but instead do ... (note that
you must include
a space after the second quotation mark)
ATDT5551212
Dial the modem, and then ...
CONNECT
Wait for an answer.
Send a return (null text followed by the usual return)
ogin: username word: password
Log in with username and password
.
Note:
Refer to the chat man page, chat.8, for more information about the chat utility.
/dev/
Specify the callout serial port.
115200
The baud rate.
debug
Log status in syslog.
crtscts
Use hardware flow control between
the computer and modem (at baudrate of
115200
this is a must).
modem
Indicates that this is a modem device; pppd will hang up the phone before and after
making the call.
defaultroute
Once the PPP link is established, make it the default route; if you have a PPP link to the
Internet, t
his is probably what you want.
192.1.1.17
This is a degenerate case of a general option of the form x.x.x.x:y.y.y.y. Here x.x.x.x
is the local IP address and y.y.y.y is the IP address of the remote end of the PPP
connection. If this option is not specified, or if just one side is specified, then x.x.x.x
defaults to the IP address associated with the local machine
s hostname (located in
/
etc/hosts), and y.y.y.y is determined by the remote machine.
Connecting to a PPP Server over a Hardwired Link
If a username and password are not required, use the following command (note that noipdefault is optional):
moxa@Moxa:~# pppd connect ‘chat –v” noipdefault /dev/ttyM0 19200 crtscts
If a username and password are required, use the following command (note that noipdefault is optional, and
the username and password are both “root):
