[aprssig] qA? Questions

I guess the biggest question here would be then, what is an igate port?
I have gone over that website (aprs-is.net) many times, and haven't  
found the answer, and also looking at the status pages for the aprs-is  

Quoting Pete Loveall AE5PL Lists <hamlists at ametx.com>:

> Per http://www.aprs-is.net/q.aspx qAO represents a packet with the   
> source call not matching the login and the client is logged into a   
> client-only port (not an IGate port).  Older server software   
> sometimes would show this on an IGate-capable port, as well.
> qAo is the same as qAO except that the logged in client had put an   
> indicator in the path showing the packet has been gated from RF.
> qAX indicates that your APRSPoint is not registered and therefore   
> cannot be used as an IGate.  qAC indicates that the client software   
> is registered.  qAX and qAC are not used on gated packets, only on   
> packets inserted directly by the client (like posit, status, and   
> message packets originated from the logged-in client).
> The only q code to be created/used by client software is qAR to   
> indicate a packet is gated from RF to APRS-IS.  All other q codes   
> are generated by the server software.
> javAPRSSrvr is used by the majority of server sysops and is actively  
>  maintained.  It has a fully functional and compliant IGate which   
> restricts its gating to RF based on digi hops.  You can find more   
> information on it at http://www.aprs-is.net/javAPRSSrvr and you can   
> find APRS-IS specifications for your own project at   
> http://www.aprs-is.net
> Hope this helps.
