It really doesn't matter what the connection device is. So long as you're connected, you can use a myriad of classes to transfer files. You could create a simple TCP socket connection using the TcpClient class, for example. If an accessible share exists on one or the other machine (or both), then you can simply use File.Copy to copy files, although this typically won't work because of default security (and anonymous write permissions are too risky). You could also go all-out and create a .NET Remoting client/server between the two, transfering files as byte[] arrays, or better yet use DIME (part of the WSE 2.0, which you can download from MSDN[^]. DIME gets around serialization, which is a big performance boost. So, just forget that a modem is connecting to the two clients and use whatever class(es) you'd like. So long as TCP/IP is the protocol connecting the clients, your options are many; otherwise, you'll need to create a Socket connection with the correct AddressFamily.
