Thanks, I found the (not yet complete) solution based on your guidance.

For anyone interested: the initialization can be done with SIRF messages. I
did not find the specific message however, only an API call
(SirfInitializeReceiverEx) in a 3rd party toolset (see
http://www.linkspoint.com/toolkithelp/SirfInitializeReceiverEx(a)GPSINITMODE@const_PGPSINITTIME(a)const_PGPSPOSITION@const_BOOL(a)const_BOOL.html) for details.

I cancelled implementing it however, because I don't want to switch to and
from NMEA and SIRF protocols.

Thanks anyway,
Balint
