Sending Raw Ethernet packet over Dial up (Modem)
-
hi there, i have an application that i want to send raw packets through dial up, i have a lan that i can send packets to easily, but it does not work for dial up i know the ways such as WinPcap, SharpPcap(managed code working with WinPcap), NDIS Driver API, that allows to send and capture packets but they only can send raw packets to lan! not to my dial up connection! any one knows how to do that?

If your modem is connected and you get an IP address, then use socket or tcpclient to create a connection. If you want to send a raw data, then use SerialPort class, if your modem is connected to serial port. Search in google about AT command.

i don't think that we can communicate with 56-Kbps Dial up Modem using cat3 twisted pair(telephone line ) with SerialPort! , by the way thanks

??? Your PC is connected to the modem using serial cable / internal modem, and not through cat3 twisted pair. If you see in control panel, your modem is connected to COMxxx. Just use SerialPort class to connect to that COMxxx.
