I haven't checked yet, but the release notes for comBIOS 1.26 seem to promise a fix for this problem, so you should probably try upgrading to that.

Im curious, did you update your bios, and if so, did it fix the
screen-spew ?

per the bios changelog, 1.26 appears to have addressed this,
   * improved int10/int16 serial console emulater

but I havent tried updating mine recently. ('download -' apparently helps)

using minicom. It seems that the trick is to type "download -" on the
soekris instead of just "download".

BTW - syslinux 3.01 is out, and it includes EXTLINUX,
a bootloader that works off of your ext2/3 filesystem.
its verry nice.

I requested a few features, which he's considering.
one of which is NOCONSOLE, which was intended to
be a work-around for the escape-sequences put in by the
video emulation.

If the bios has fixed that problem, I should scratch that
off the request-list b4 he goes and implements it.

But I dont have my box at hand to try upgrading myself currently.
