Connect to remote server (2003) via phone line

I need to write an app in .net that will dial a remote computer and download some files. Where to start?

Thanks in advance.

I'd start with ZModem source (ftp://ftp.cs.pdx.edu/pub/zmodem/ - you want rzsz in any of its forms). It's written in C, but it's not too difficult to translate (it's been translated into just about every computer language that could do the things it needs). Dialing the phone is simply giving the ATDT command and the number, and answering it is simply giving the ATH1 command when RI becomes true. (Use the MSComm1 control.)
