Not knowing the Standard well, I don't like if( left || right ) where
"right" depends on "left".  Maybe the Standard guarantees it, but it
looks messy.

	How about:
BOOL	bRF;
 gotoxy(1,10);
 cprintf("REC: ");
 clreol();
 totalread = read = 0;
do{
    for(x = 0; x < read; x++)
          cprintf("%X ",Com.received[x]);
     bRF = ReadFile(Com.handle,Com.received,to_read,&read,NULL);
    totalread += read;
    to_read -= read;
}while( bRF && (read != 0) );
  if( !bRF )
	read error;
  if( to_read != 0 )
	short read error
    
Needs a lot of work, but I think you can get the idea.
For instance, you could change to this
ReadFile(Com.handle,&Com.received[totalread],to_read,&read,NULL);
and move the display to after the while.
