system(3) does a fork and exec, to put it simply. You might want to look at popen(3), which returns a FILE pointer that allows you to read output from or write input to the command that you're executing.

Edit: Aaaand I just noticed that pludi has suggested exactly the same thing.

NAME
term::send - General output to terminals SYNOPSIS
package require Tcl 8.4 package require term::send ?0.1? ::term::send::wrch chan str ::term::send::wr str _________________________________________________________________ DESCRIPTION
This package provides the most primitive commands for sending characters to a terminal. They are in essence convenient wrappers around the builtin command puts. ::term::send::wrch chan str Send the text str to the channel specified by the handle chan. In contrast to the builtin command puts this command does not termi- nate the string with a line terminator. It also forces an flush of Tcl internal and OS buffers to ensure that the characters are processed immediately. ::term::send::wr str This convenience command is like ::term::send::wrch, except that the destination channel is fixed to stdout. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category term of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. KEYWORDS
