Just to let you know.  I was talking with an AT&T Technician who was
repairing a port board asked if I knew about the "lockup chip replacement".
I would call the AT&T hotline (whether you have support or not) and mention
that you heard of a chip-replacement for the port board.  It might well
be the UART, I am not sure what it is, or if it actually exists.
