I will graph them this eve. The tools to do so are open source (imagemagick and gnuplot) and both of those applications are built for windows, mac, linux, etc. so if anyone wants the graphing scripts, i will put them on some webspace.
I asked before, but maybe i can ask again.. is anyone interested in developing some graphing code that will run on the modem itself. It would present its graphical output via the Huawei's web interface. The new code would be written in C and built for the mips processor on an x86 PC using the open source GNU c cross compiler toolchain. Pre-built cross-compiler toolchains are available from here .
The graphing tool would either get its line stats from parsing the output of xdslcmd or it could query the xdsl driver directly. The main difficulty, as with all embedded code, is that it must be lean, and most image encoding libraries are enormous.. The libjpeg C function library can apparently be stripped down to the bare essentials, so it might just fit in the firmware.
Since the firmware in the hg612 shares much in common with other Broadcom-based devices including, it seems, the same ioctl() interface to the xDSL device driver, the graphing code should run, perhaps with a bit of fettling, on those devices, too.
