[Oberon] Oberon and TLS; was A2.

[eas lab]

Peter, this old post only read now, since I lost my Gmail access.

No, I just want to fetch my gmail; but they use TLS. And I want to
use ETHO's system: where you can see/edit several received & pending
texts, at one time, together, and you can freely edit a new/extra
"Cc: entry", instead of a KFC pre-baked mentality thing where you
must scroll to the top/or-bottom to read the controls, and lose your
place in the text.

Yes, I know about that. When I restore Linux-Oberon I'd like to be
able to use that; but I don't find the documentation of how to
interface his SSL to the mail-client and the ppp-transport.

Or since LEO apparently interfaces to the linux <tcp/ip - sockets>:
if perhaps linux can do the SSL?

I'm still trying to get Win-x64 httpS *TEXT-based* access.
Full-browser http is intolerable, although perhaps not wikipedia.

OK, that could be a tidy way to do it, because I can test the stages
independantly. Have you tested a linux based ETHO communicating
to <local host>? I've got a working RPi:ALO, but I've never confirmed
if/that ALO communicates with the underlying linux <tcp/ip>, like LEO
does.

Nor do I understand how it works - at a physical level, compared to
the old days, where the bytes where sent to the serial-port to drive
the modem; so you could visualise the passage of bit3 of char("A")
on its route to creating an audio-fequency wave of a calculatable
duration, on the telephone-line.

I miss my access to Guenter Feldmann's LEO which integated ETHO's
magical interface with the inet and file-system of the underlying
linux.

---- How would ETHO modified to ride-on-linux access <local host>?
AFAIK: whereas <local host>'s *contents* is in the linux file-system;
the <local host> is accessed by the <socket-system> which I know
nothing about?
