Robert,
 Here's a quick-and-dirty routine to get one byte from a path you have
previously opened with open() (or use path = 0 for stdin).
 cread(path,buf)
 int path;
 char *buf;
 {
      int cnt;
 
      if((cnt = _gs_rdy(path)) < 0)
           return(cnt);
      if(cnt == 0)
           return(cnt);
      return(read(path,buf,1);
 }
 
 This should read just one byte. If there is nothing there, it returns 0.
Obviously if there is an error, it returns -1. Hope this is a good starting
place for you.
 Mark
