With regards to "remote control":

You can do it for free by typing "CTTY COMx:".  After executing this
command, your console is redirected to the serial port named.

Note that to get back to the normal console, you can execute a CTTY
command with no argument, or reboot.  Also -- programs which do direct
screen & keyboard I/O (ie: don't use the BIOS calls), or anything
which tries to go into graphics mode won't work.

To do this, you need a package such as Carbon Copy (tm).  There
are many of these available, most require two copies (they check
serial numbers, and won't work with themselves), and they are
a little expensive.... Other than that they do work.
