[Nut-upsuser] Unsupported UPS Orvaldi 520PL?

I am new to UPS stuff, please be patient with me ;-)

Archlinux i686, kernel 3.0-ARCH #1 SMP PREEMPT.
nut 2.6.1 installed from source via Arch's AUR repository.
Mother board GA D525TUD with two serial ports, both enabled in BIOS.

I got some old Orvaldi 520 PL UPS [1], which is supposed to be
supported by the vendor [2] with sw called UPSmart. The statically
compiled i386 binary ran but did not detect the UPS.

I also tried openupsmart [2] (obsolete now), but UPS was not detected.

Since NUT compatibility list shows some success with blazer_ser driver
for some other Orvaldi UPS, I gave it a try on both ttyS0 and ttyS1 -
but no success (see the log below).

I have also read about the cable variants and their configuration in NUT
- Orvaldi uses some special serial cable with pins like shown here [4],
which is not described on NUT doc pages. 

If there is any chance it could be supported by NUT, can anybody give
some idea how to move on?
