tcp/ip utility for testing network connections/ports
Sender is a windows tcp/ip client/host that lets you send and recieve text to and from tcp/ip ports. It now has a hex mode so that you can send any 8bit byte combinations. It can be used for testing simple pop and smtp connections (original project reason) or for any other protocols for which you may want to test by hand from windows.
