[aprssig] Nuvi 350/Tracker 2

[Scott Miller]

Hi Jon,

It seems to be a bug in the current T2 code.  When you send a message on 
the nuvi, the T2 sees it in the outbox and starts transmitting it for 
the number of retries specified.  When the retries are up, it's supposed 
to send an ACK to the nuvi to get it to stop trying to send.  Otherwise, 
it just shows up like a new outgoing message and the cycle starts again.

It works when the message is ACKed by the receiving station, but not 
when the retries run out, despite being basically the same bit of code. 
    I'm still working on tracking down the problem and should have a fix 
in the next release.

I'll also probably have it send a message to the nuvi that the outgoing 
message timed out without an ACK - otherwise there's no way to tell 
whether it got through or not.
