Oh well, any other suggestions?

Any other takers willing to help me out?

Right.  I misunderstood you and thought that was what you mean (as in
DOS-specific).  I didn't understand what the termios functions were.

I looked up termios in the RHIDE help and found out that it was above my
head.  I would rather just clarify my problem w/ the istream::get() problem
rather than tinker with the termios functions (which I don't understand and
don't need).  Any help with my problem would be greatly appreciated.
