| connect '....' | : The modem connection is made with the program 'chat'. The for chat needed information is stored in the file nt_callback.chat (That is what -f means). The file nt_callback.chat is explained below. The parameter -v means that all log messages are stored via syslogd in /var/log/messages. |
| crtscts | : Use hardware flow control |
| bsdcomp 15 | : Use bsd-style compression |
| lock | : Lock the modem |
| debug | : Activates the debug mode. All messages are stored in /var/log/messages |
| lcp-echo-interval 20 | : see 'man pppd' |
| lcp-echo-failure 2 | : see 'man pppd' |
| 192.168.0.3:0.0.0.0 | : Definition of the remote and local ip addresses from <local_ip_addr>:<remote_ip_addr> |
| name "domain\\my_login" | : Your NT user name. This has to be the same as in chap secrets. The safest way is to use domain\\user form. |
| remotename "inbelnt" | : The name of your NT server. PPPD uses this for the chap secrets file. |
| -detach | : Detach from the controlling terminal. PPPD will fork to become a background process. |
| receive-all | : This is for buggy OS's, like MS that handle the asyncmap not very well |
| TIMEOUT 120 | : Disconnect after 60 seconds if there is no response |
| ABORT "NO CARRIER" | : Abort if the modem report no carrier |
| ABORT "BUSY" | : Abort if the modem is busy |
| ABORT "NO DIALTONE" | : Abort if you have no dial tone |
| ABORT "ERROR" | : Abort when the modem reports error |
| "" +++ATZ | : Initialize the modem |
| OK ATE1Q0&C1&S0 | : Initialize the modem |
| RING ATA | : Wait for a call |
| CONNECT "" | : Wait for the modem reports a connect |
