I have already posted in the SeaBIOS mailing list
about the feasibility of that, but my follow-up
is waiting moderator approval for nearly a week.

In the meantime, I have a "terminal" program on
the PDOS/386 disk which does the INT 14H call,
and when run under Bochs I can redirect it to
an arbitrary TCP/IP address.

I also have a "virtual modem" designed to accept
the ATD request - this was first tasked to do
ASCII to EBCDIC translation so that I could
connect to an EBCDIC BBS. You can find that here:

https://sourceforge.net/p/mvs380/mvssrc/ci/master/tree/ozpd/c/modem.c

All components in that chain are pretty flakey at
the moment, but it did work sometimes, sort of.

I'm more likely to get that process working first,
so that you can connect an old PC to a modern
PC using a serial to USB cable, and access the
internet using PDOS/386.

At some point I will investigate what sort of
laptop I can buy that allows me to flash
SeaBIOS or some alternative.

Another thing that might delay SeaBIOS is that
I might have a BOOTX64.EFI that reinstalls a
BIOS on computers that have deleted it, and
as part of that, I can direct INT 14H to
something interesting. But I think there is
nothing interesting available via standard
UEFI, so I would have to resort to something
that is hardware-specific, so I am likely to
forget trying this, and instead go the
SeaBIOS route.

Probably in the medium term I will instead
run PDOS/386 natively from USB stick on a PC
that has BIOS support, and when I need to
gather UUCP news or whatever, I will reboot
to the hard disk or a different USB stick to
use something that has the required Wifi
drivers, ie either Windows or Linux, and then
run Bochs so that PDOS/386 has access to a
serial port thus the internet.

But yeah, I'm really keen to get PDOS/386
talking to my dumb phone which has bluetooth.
And my dumb phone has internet access, so
I don't know if it is possible for an app
to run on it that passes the bluetooth
data stream on to the internet. It's an
Alcatel One Touch. I have never owned a
smartphone. I only have this dumb phone
because my provider gave it to me for free
to stop using their 2G network. They sent
me so many SMSes telling me to get off the
network or I would lose my access, but I
waited till the bitter end, because I
was in a debate with someone whether my
Nokia N95 supported 3G or not. It didn't,
but the other guy still didn't give up, and
tried to get me to get a SIM from a different
provider. Since that required physical
movement, I decided to just let him continue
believing that he was right.

BFN. Paul.
