Hi Liam,

There is for example Dillo, which is not bad, but graphical:

> A DOS app can be a maximum of about 620-630k of memory.

This is not true for apps which use DOS extenders. Those
can use several gigabytes of memory. There even are some
proof of concept extenders which let you use more than
4 GB of RAM.

You can use text oriented browsers such as LYNX, LINKS,
W3M, ELINKS and similar. The problem often is that they
do not support javascript or modern HTTPS protocols.

> There is no wireless LAN support for DOS that I know of.

Only some ancient PCMCIA WiFi cards have DOS drivers,
but you can use an external bridge box to connect to
your WiFi by LAN cable.

You could of course also use Linux, which also has some
screen reader and Braille friendly distros, but as the
question is about DOS, the real question is which text
oriented DOS web browser supports tunein.com As expected,
it relies heavily on javascript, but you could probably
write a parser to extract the actual stream locations.

I believe such things have been done as Arachne plugins
for youtube, but they are chronically outdated, which
probably makes them non-functioning on current youtube?
Arachne is a graphical web browser for DOS.

https://tunein.com/radio/home/

According to https://www.ssllabs.com/ssltest/ about
tunein.com, the site does not support SSL 2 or 3 any
more (which is good, those are old and insecure) but
it supports TLS 1.0 to 1.2, although sites SHOULD not
support TLS 1.0 or 1.1 (also too old) and SHOULD have
support for TLS 1.3 already.

Supported modern ciphers‌: ECDHE RSA with AES256 or
AES128 GCM, ECDHE + CHACHA20 POLY1305, all with
either SHA256 or SHA384.

Supported outdated cipher components: AES128 or
AES256 CBC, RSA without ECDHE.

The site would use TLS 1.0 on the following old
software: Android 2.3 to 4.3, Baidu 2015, (MSIE 7
to 10 on old Windows: Firefox or Chrome on Windows
XP would already use TLS 1.2), Java 6 or 7, any
OPENSSL 0.9 based software, Safari 5 and some 6.

So a browser for DOS which wants to be able to
use the site at all via HTTPS will have to use
OPENSSL 1.0 or newer or another SSL/TLS library
which supports at least TLS 1.0 but preferably
TLS 1.2 or even TLS 1.3 to be future-proof.

Can some DOS browser users here tell me how modern
the HTTPS compatibility of their preferred DOS web
browsers is at the moment?

Note that "Retrozilla" can give you TLS 1.2 HTTPS
and HTML5 even on ancient Windows 98, 95 and NT (!)
based on a fork of SeaMonkey 1.1.19, but even that
is not modern enough in terms of multimedia codecs
and javascript compatibility to view Youtube clips.

Regards, Eric
