The command is +GTRAT. I can't find any public AT command manual for
MA510/MC610, but this "L8-Family" reference is very similar:

In an ideal world we could discuss this openly, I could get help and finally
submit patches upstream. As it is, I think we need to keep our patches internal.
So I guess my question is: how would you solve this? As you say, this is "not
very well managed right now", so I wonder if improvements can be made to how
RATs/capabilities/access techs are handled without going into the details of a
particular modem. I'd be open to give this a shot and submit upstream patches
with some guidance :)

Really wish I could be of more help.
