Let me start by answering this, noting that my goals
are not set in stone, and have changed even recently.
First of all I don't want to rely on the internet.

I have done further exploration and have a new proposal.
I found that USB to serial port adapters are not standardized.
So instead, what about adding NDIS to do USB tethering plus a tcpip stack
to create a virtual modem that would allow you to do:
ATDnews.eternal-september:119
Then I could
I have a new variation on this problem.
I have a Chromebook with seabios loaded.
But the Chromebook doesn't have a serial port.
I could get a USB to com port adapter.
But I would like seabios to drive this so that I can use int 14h in my os.
Is that something that exists or could be added?
Hi Gerd.
Thanks for your reply. Sorry for the delay, was swamped
with other things.
Currently I don't know what to recommend, because I
don't understand the other side of the INT 13H/14H,
only the OS side.
Well, the other side talks to the hardware,
and needs drivers to do so. See src/hw
Hi Peter.
Thanks for your reply.
Sure. Implement a driver for that redirection which behaves as an
int14h handler and place the address of its entry point at address
:0080. (14h*4)
The method works with any BIOS.
I would like it to work with any OS that uses INT 14H

Hi Peter. Thanks for the great info.
Ok, the main thing is I don't want my OS to have to load
this, I want it loaded before the OS is loaded.
I understood that, and an option ROM satisfies this.
Ok, thanks for confirming.
The bare board only needs power to run, everything is onboard.
