..NET 2.0+ has a serial port class you can use to connect via modem.

To send a file, you'll need to use a protocol such as X-modem, Y-modem, or
Z-modem ... There are several libraries that implement modem transfer
protocols.

Knows any internet page that have an example that use this class and
implements the protocols that you say.

Thank you anothertime.

Its name should be SerialPort Class. You can find in Toolbox also.
Just search Google for samples, however these may help you.

Hi,

You can download XMCommNET.dll from my homepage. It supports XMODEM file
transfers, and it is free.
