I’ve been looking for a free telnet program for Windows, that had the ability to upload and download files using Xmodem, Ymodem or Zmodem. I wanted this in order to move files from my Windows PC to my Apple //c.
I found one this morning. It is called ExtraPutty and is a branch off the original Putty program that adds Xmodem, Xmodem 1K, Ymodem as well as ftp. I’ve added ExtraPutty to the links.
In the past I have had to resort to moving the files and the ADTPro cable to my Linux PC and then move the file over to my Apple //c. Now I can just use ExtraPutty to transfer the file or files to the Apple //c using the ADTPro cable as is.

MS Hyperterminal does file transfer and is included with Windows (at least it was with XP … don’t know about 7/8)
