4 weeks and 500 compilations later isn't enough patience? Thanks though. 

_kbhit would do what I want. I found that one of my problems was I was
calling ipfx(0) to force the output to draw on the screen. I didn't realize
that it was caching a keypress as well. After getting rid of that, things
worked a little better. I found that fflush(NULL) flushes both in and
output buffers which is exactly what I wanted. Having residual chars in the
input is what started me down this path to begin with. Thanks again!
