Yeah, that's the problem.  Setting that TLV makes the command return
"Success" on the ADU960s, but I'm not able to actually *see* any
messages using MT_READ or MT_NOT_READ.  Also, when sending an SMS, all I
get from the ADU960s is the "Transfer Route MT Message" indication,
which MM currently ignores.  That data looks like it contains the PDU,
right?  Maybe this firmware simply can't store the message to NV so it
indicates it to the host and then discards it, and that's why it doesn't
show up in SM/NV storage?
