But wasn't the conclusion of this discussion that you can just buy one, connect
it to computer only for booting, and then disconnect it and use on another one?
Somebody mentioned serial ports not being "hot-plugable". This is not a concern
here, as the serial port is built into chipset and remains there - you are just
moving the connector.
The connector/adapter you need is something like this:

the pinout is only informally "standardized", so it is best to check it in advance.
Alternatively, instead of buying it, you can find such bracket (usually with one
DB-9 and one DB-25 port) on old (very old!) PCs. I found mine many years ago in
some old 486 waiting to be recycled.
