NB:  It's quite common for serial ports on computers, these days, to be
nothing like "standard RS-232".  That can be a problem for some devices
that you want to connect to it.

I'd be trying some tests by connecting two computers together, and
seeing what you get.  Or plugging in an old modem, and doing the old ATI
command tests, etc.
