How to use modems with Vb.net?

P: n/a
RD
I can't figure out what to use to be able to receive a file via a modem in
Vb.Net?

The requirement is that users can dial in and send an ascii file using a
modem.

Anyone know where I can find some sample code for this type of stuff?

In VB6 we could get 3rd party controls but I can't find anything similar in
the new environment.

Thanks for any help

Hi,

There are several ways, at least one free and some that cost money.

You can use XMCommCRC.ocx from my homepage (it works fine in .NET; I have
example code in my book). The file transfer protocols that are supported
are XMODEM/checksum and XMODEM/CRC. There may be other free solutions, but
I am not aware of them.

There are a number of commercial serial communications controls for .NET
that support file transfers (Sax Communications .NET for example,
www.sax.net) and others. Also, any ActiveX control that you used in VB6
still will work under .NET.
