Hi
 One of the other problems was that even which bits were use
to handshake the transmit and receive could change depending
on how one wired the board, so just knowing the port is still
no enough. Any commercial software that didn't go through
the BIOS was asking for troubles since there was no way
to determine how the console was done. On some systems it
went through a video board and not serial, at all.
