If I understand the question a ready made solution that converts serial data to TCP is ser2net. I've used socat to create a virtual serial port for minicom and cutecom but have not tried a raw connection with PuTTy
Shell-based pipes buffer different amounts of data until told to flush. While piping from the shell may work in a pinch, you'll start to get odd delays. Symptomatic of this that the c program is always waiting for data. Since you are working in C, it may be more efficient to open your own network sockets and dealing with those putty connections a little more directly. Depending upon what you are doing, you might also be able to open local or remote tunnels in an ssh connection to move TCP traffic around w/o needing to manually handle network sockets.
