BT Voyager 210 UART found, no docs, BusyBox

Hi there,

Please forgive me if I don't fit the usual tone and style around here, i'm new and just created my account.

So, after spending the last two hours and having great success with the V2 version of this BT box managing to get OpenWRT installed and happily running after soldering a UART header to the board, I wanted to look at another device I have, the BT Voyager 210.

I've identified the UART pinout for this device, and handily there is a header for this. Heres the board with the "front" at the bottom of the image:

The little white connector in the bottom left, just left of the bicolour LED is the UART

From Right to Left pinout: 3.3v GND TXD RXD

After starting the device with 115200 baud connected, I can see that the device is running
==> Bcm963xx Software Version: <== BusyBox v0.60.4 (2005.09.26-02:56+0000) Built-in shell (msh)

Username and password are both admin

You get a main menu which comes with the device (this also appears to be accessible via telnet too) and if you ignore the menu you can type sh and drop to a BusyBox shell.

It says I can type help for commands like normal, but this is an unknown command. ls is also unknown, cd works and pwd also so you can navigate around directories, wget is a no, tftpd is a known command but responds with tftpd: daemon bind failed: (null), vi and vim are unknown, echo and cat work, ping works.

command busybox outputs:

BusyBox v0.60.4 (2005.09.26-02:56+0000) multi-call binary

Usage: busybox [function] [arguments]...
   or: [function] [arguments]...

        BusyBox is a multi-call binary that combines many common Unix
        utilities into a single executable.  Most people will create a
        link to busybox for each function they wish to use, and BusyBox
        will act like whatever it was invoked as.

Currently defined functions:
        [, busybox, cat, df, echo, expr, false, halt, ifconfig, init,
        insmod, kill, klogd, linuxrc, login, logread, mkdir, modprobe,
        mount, msh, ping, ps, pwd, reboot, restore, rm, rmmod, route,
        sendarp, sh, sysinfo, syslogd, test, tftpd, true, tty, wol

Pressing space at boot interrupts boot and drops us to a prompt CFE> and when we run help we get the following commands listed

Available commands:

w                   Write the whole image start from beginning of the flash
e                   Erase [n]vram or [a]ll flash except bootrom
r                   Run program from flash image or from host depend on [f/h] flag
p                   Print boot line and board parameter info
c                   Change booline parameters
f                   Write image to the flash
i                   Erase persistent storage data
b                   Change board parameters
reset               Reset the board
flashimage          Flashes a compressed image after the bootloader.
help                Obtain help for CFE commands

For more information about a command, enter 'help command-name'

Not sure is it'd be possible to get more commands available or even if we could get OpenWRT working. I don't have the experience with that.

Getting and posting the full boot log from serial would certainly provide people with a lot of insight into the possibilities and challenges.

Broadcom means that the xDSL modem isn't supported in the first place, but beyond that - 8 MB RAM (and 4 MB flash) are unusable anyways.
