Sending binary files using the NET command

[Junkhead]

I wrote a fileserver that allows one to download files from a central server. However, currently it has two limitations:

1) Only one client can connect at a time
2) It can't send binary files (.exe's, .zips, anything that isnt source).

I'm focusing on issue #2 for now. How can you send binary files using the NET command? I run into illegal character errors whenever I try. I've tried using read/write, put/get, and it doesn't make a difference.

Anyone know what to do?
