Charles made a good comment on a protocol difference (padding) that may
make it worth to create a blazer derivative.
but I'm not yet sure since it could well be another communication
subdriver, as in the USB version...
I have in mind, for some time now, to create a more advanced version, that
would support Q5 (a superset of Q1), i.e blazer 3rd generation (counting
the first 'megatec' driver).
I need to think a bit more, and check a few things.

knowing that you don't have your SMS handy, for the time being, that would
be good if you could familiarize with blazer and the general design of NUT
driver. it will be useful in all cases.

anyway, considering the easiness of creating a NUT driver, you may end up
porting it very quickly as a new driver, and have Rodrigo testing it. as a
second step, we can check for a potential driver consolidation.

theoretically, it should be 'T<n>' where <n> is a number of minutes from 01
to 99.

in NUT, we just have a way to request a quick test ('T', such as in your
driver) and a longer one using 'TL' (running until low battery):
(from blazer.c)
401:        { "test.battery.start.deep", "TL\r" },
402:        { "test.battery.start.quick", "T\r" },

Rodrigo answered this point to me privately, then again to the list:
04b4:5500
