For the DOS boot disk, I think this is just a property of your BIOS;
either it supports using serial as a console, or it doesn't.  DOS uses
the BIOS for I/O; I believe that is what the the "IO" in "BIOS" is all
about :-).  But I could be wrong.  Have you tried it?
There is the "BIOS redirection" feature that some BIOSes have.  We've 
got some machines that will do that (redirect the console to the serial 
port, even after the OS has booted).

But I was talking about the install.pl itself using the serial port. 
Just as a terminal program (for example) can run in DOS and communicate 
with the serial port, regardless of the BIOS, so too could install.pl do so.

The only thing that I've been meaning to try is:
a:\>MODE COM1:96,N,8,1
a:\>CTTY COM1
I've still not tried this (trivial though it is), as we've been 
super-busy at work.

For Linux, I have added support for serial hardware and serial console
to the kernel for 4.0.  So you should be able just to boot the kernel
with the option "console=ttyS0,9600" or somesuch.  If you are booting
from the network, you can do this by editing the "append" line in
tftpboot/pxelinux.cfg/default.  If not...  Then it's harder.
Ok, I'll have to follow up with the linux setup.  What all is needed to 
upgrade from the version I am on (3.5 or something like that) to the 
latest version?

Are you booting these systems from floppy, CD, or network?
PXE booting off the network, primarily.  Occasionally, I use syslinux to 
boot the same floppy image off a USB "pen drive".
