Hello everyone,
(This is a repost. The first copy, on 18 Sep, was bounced by my uplink -
I posted it sixteen minutes after asking AreaFix for this echo, so at
that moment I was not yet an active link here and the message went to
badmail. My mistake, and my apologies if it arrives twice somewhere.)
A word of warning first: I do not speak Russian. I read this echo
through a machine translator, and I am writing in English because my
outgoing mail leaves here as CP437, which cannot carry Cyrillic at all
- a Russian text from me would arrive as a field of question marks.
Answer in Russian if that is easier for you; I will run it through the
translator the same way I read the rest of the echo.
I am writing from Warsaw. I run the BBS "DEAD SOCKET" (2:484/101) and as
of this month I am the NC of net 2:484. My line is not an ordinary one:
a US Robotics Courier V.Everything 25 MHz with ID_SDL 4.03d firmware,
connected through a Cisco SPA122 VoIP gateway. There is no copper
anywhere in the path, and the modem still holds V.34 at 31200.
I am looking for Konstantin Norvatov`s KN_SDL firmware - versions 0.F
and 0.F/BugFixed, files kn_f_20.zip and kn_f_25.zip. They lived at
ftp://ftp.usr.spb.ru/courier/kn_sdl/0.F/
Already checked and empty: ftp.usr.spb.ru and usrmodem.ru are both gone
(the domain no longer resolves); the Internet Archive has only HTML
pages from them, no files. I did recover Vavaev`s archive through the
Wayback Machine - AVC-56K is there (2.2, 2.3 beta, 2.4), but no KN_SDL.
Nothing on old-dos.ru either, nor in the "Polygon of Ghosts" threads.
If anyone still has these two files on an old disk or a CD, I would be
very grateful. I can accept a file attach at 2:484/101, or download from
wherever you point me.
While I am at it, I am also missing these ID_SDL builds: 4.00
(idsdl400.zip / id25_400.zip), 3.04 (idsdl304.zip / id25_304.zip), 4.01c
for 25 MHz boards (id25c401.zip), and the documentation id401doc.zip /
id402doc.zip.
Not empty-handed: I have put together an archive I will gladly share -
ID_SDL 4.01c/4.01d/4.02d/4.03c/4.03d for 20 and 25 MHz, 3.02, AVC-56K
2.2/2.3b/2.4, the official SDLs (US/Canada and international, including
7.6.7), V.92 images for the Courier 3453B and 3453C, documentation, and
the xmdflash flasher. I can send it as a file attach, or put up a mirror
on my own server if that is more useful to people.
Why I care: a line over VoIP behaves like a very bad analogue one -
jittery delay, clock drift, lost packets. Firmware that was tuned back
then for poor lines works noticeably better here than the factory
builds. By all accounts KN_SDL has "a colossal number of adjustments" -
exactly what a path like this needs. If anyone has experience tuning a
Courier for VoIP, I would be glad to hear that too.
Best regards,
Grzegorz Worona (kombos)
