May I suggest 3 ideas for Xastir after few years of use ?
1- Queries
It should be great if Xastir could answer APRS queries (?aprsh or ?aprsd for
instance, and others). These are really usefull to test stations capabilities
especially on HF (or other bands of course) when propgation is good !
Some queries are implemented in src/db.c:process_directed_query() and
process_query(). Others could be implemented there fairly easily if someone had
the time/desire to do so. I don't have the time right now but perhaps someone
else will pick this up.
2- Message timer
Other stations, digi or igate, are sometimes slow to react facing Xastir
which retry a message quickly after the first sent. I noticed this
"aggressive" behavior especially with slow links (300bds HF).
Can we imagine an adjustable timer for this parameter ?
Because it looks progressive when retries are growing (APRS specs ?), 3 steps
could be possible :
- quite
- normal
- aggressive
As I recall Xastir does an exponential backoff on message ack's up to a max
delay. The initial delay is optimized for 1200-baud simplex links but it
quickly backs off: There shouldn't be many transmissions before it backs off
sufficiently for any link speed.
I'm not sure another scheme is warranted here but that initial delay could
perhaps be made changeable. It would require several files to be changed
including the GUI.
3- Data and messages views
Data view and messages view are really usefull to monitor trafic but I think
date and time informations are missing.
How about add this in a short field for each line on these monitor windows ?
Seems reasonable as long as the windows don't get extended horizontally much.
Alternately could throw timestamps in on another line above them and not extend
the window.
