[Xastir] Xastir and another APRS program

[MLHPUB]

Hi all,

Maybe a "stupid" question ?

On a Linux computer, I now run Aprx full-digipeater F4ACU-3 (defined 
like this with "mycall") with one AX25 port defined as F4ACU-3 in 
/etc/ax25/axports and I want to add a graphical view with, of course, 
Xastir.
I know it is possible to use multiple programs with the same AX25 port, 
what I want to do.

In this case, how should I configure Xastir for "mycall" parameter ?
-> if I use F4ACU-3, this callsign will be both for Aprx and Xastir. Not 
really good.
-> is it possible to use F4ACU-0 with AX25 port defined as "F4ACU-3" ?

Thanks for your help !
