CommNet is a Windows software that facilitates dial-up and Telnet connections through the internet. There's also the availability of a secure version of the software called Secure CommNet, which enables SSH2 capabilities.

If you're looking specifically for file transfers, CommNet is an excellent choice. It supports high-performance Zmodem file transfers for both dial-up and Telnet sessions, as well as Ymodem-G for dial-up sessions. For Telnet sessions, users have the added ability to leverage FTP capabilities. Meanwhile, the software offers TTY, VT100, VT220, PC ANSI, and SCO ANSI terminal emulations.
One of CommNet's most unique features is its Telnet Host Mode Server, which lets other Telnet clients connect to the user's system for chat and file transfer tasks. This handy addition helps make CommNet an all-in-one solution for communication and sharing.
As an added bonus, CommNet also includes a built-in Phonebook and expanded scripting and command-line options. For those who require an extra layer of security, there's also a Secure CommNet option that comes with SSH2 capabilities.
Overall, if you're in need of a software suite that can handle all your internet connectivity needs, CommNet is definitely worth checking out. Its feature-rich design and ease of use make it a solid choice for users of all experience levels.
