Your NetWinder's PPP dialer allows you to connect to the internet using a modem. If you have enabled Packet forwarding as described in the Ethernet Settings section, other computers on your network can use the NetWinder as a default gateway, and access the internet through the shared modem device.
When you click on PPP dialer from the Network configuration page, you will see a page that looks like this:
If you click on the words Edit the dialer configuration, you will then see the following page:
The options are as follows:
Init string. This is the command to send to the modem to initialize it. Unless you have problems, the default of ATZ is probably correct.
User name. This is the login name for your internet account and is provided by your internet service provider.
Password. This is the password to your internet account and is provided by your ISP.
Phone number. This is the phone number of your ISP's modem pool.
Note: this is unrelated to the actual modem speed, which is determined automatically. It is almost always best to choose 115200 here, unless you experience problems connecting.
Flow control. If the NetWinder is sending data too quickly to the modem, the modem needs to stop it somehow. There are two techniques for this. You should almost always use Hardware flow control, which is faster and more reliable.
Local IP address. This is the address assigned to your NetWinder by your ISP. Usually, you will turn on Dynamic IP support below, and this address will be determined automatically.
Remote IP address. This is the address of your ISP's server. Usually, you will turn on Dynamic IP support below, and this address will be determined automatically.
Dynamic IP support. If this is set to Yes, your NetWinder will request the Local IP address and Remote IP address options from the ISP when it connects. This is almost always the correct thing to do. If you experience problems, you can try entering the values manually and switching this setting to No.
Dial mode. This determines when the NetWinder will try to connect to the internet. You have two options: On Demand, which will cause your NetWinder to connect to the internet whenever someone on your network tries to access the outside world, or Up from...to, which asks the NetWinder to keep the network connection running full time during certain hours of the day.
