Prestige 643 router/modem

Does anyone know where I could find a detailed manual for the Prestige 643
router/modem?

It's quite an old model (though it happily does > 6Mbit) with quite a
complex command line interface that has much more flexibility than going
via http. For a start, I was only able to input my ISP username via the
telnet interface, the web page restricted the maximum length too severely
for it to fit, despite the fact that the memory space to store it
obviously exists.

Telneting takes you to a sort of BBS style ANSI interface, with a CLI
option a couple of menus down.

The commands run numerous levels deep, with each level having it's own
subcommands.

eg IP WAN ADSL RDATA <Argument>

While the inbuilt 'help' is useful to the extent of listing the commands
and telling you something about what arguments are expected, it doesn't
give enough detail to work out exactly what's going on and I'm fairly sure
I could cripple it bad style if I tinker carelessly. I can't even find the
hardware reset-to-defaults button.

I'd also like to figure a way of 'hacking' back to the OS that's almost
certainly in there somewhere behind the 'BBS' application.

What I'd *really* like is some reverse engineering hints or disassembly;
if at all possible I'd be interested in tinkering with the flashable part
of the (ee?)ROM.

Any hints would be very very welcome. If anyone actually has original
documentation files that are too big for email and doesn't have easy
access to a webhost I'll happily set up a dynamic URL pointing to a
web/cgi or (preferably) FTP interface on my home machine so they can
upload them.

If anything needs emailing, probably best to warn me, though certainly
make sure it's to the 'reply to' address rather than the 'from' field on
this posting.

Thanks..

Strangely Zyxel seems to have lost the documentation for this, although
the relevant directories are still on the FTP server. I found a copy of
the manual here:

Is there anything in the directories or are they just blank?

I didn't think of digging around for FTP links as somehow I thought it was
all http. I'll shuffle through the site. Oops! Gotta go be an ambulance.
Makes a change from taxi driver I guess. Thanks for the help.

Just empty subdirectories, like

ftp://ftp.zyxel.co.uk/P-643/user_guide

Ok.

Nice one for the first reply. There's more than enough information in that
manual to get to grips with the router's full capabilities. It's got
assorted commands that ring bells from a Cisco networking (routers et-al)
course I did a while back, certainly more than I'm used to seeing on the
current domestic toys. A few things to experiment with, though I don't
think my little network with its single public IP has much need of RIP2.
:`) The filtering might be interesting to look at though.

I don't suppose you (or any other helpful folk) have any hints on wangling
past the telnet UI to the OS I'm convinced is hidden in there? I'd love to
lift the lid..

I'll be away for a while after the 24th but I'll be checking this group.

Anyhow, the manual was the main thing I needed. My thanks for that.

First glance, looks a perfect fit. Lots of interesting tidbits.
Used in a wider selection of hardware than I expected. Please excuse
brevity, something like 4:00am the last time I looked.. :-)

Thanks.
