Output text file to TCP port

Question

How can I output a text file to a TCP port on Windows Vista using built-in software? For example,

type TextFile.csv | telnet localhost 1979

This doesn't work: The process tried to write to a nonexistent pipe.

Shouldn't this be moved to Super User? – Cristian Ciupitu Sep 14 '09 at 15:12 — Cristian Ciupitu, Sep 14 '09 at 15:12

The tool to use is probably the windows ports of netcat.

If you're at work, some AV applications (McCrappy) will identify netcat as a virus. – duffbeer703 May 19 '09 at 21:48
SEP identified it as a virus, and it worked great. I replaced "telnet" with "nc" and the pipe worked as expected. Thanks! – George Tsiokos May 19 '09 at 22:00
