Kenwood, modern Yaesu rigs and many SDRs use an auto information
mechanism that broadcasts unsolicited rig state changes, Hamlib does
not support this and turns off the function. Because several passive
devices rely on this information to detect band changes for example
this change adds code to save the AI state on start up and restores it
on exit. These devices do no need the broadcasts since when an
application using Hamlib is running as necessary state polling by the
application provides continuous rig state updates.
Got a confirmation from Kenwood that the "TY" command returns "TYE 00"
or "TYK 00" for European or USA firmware.
So here's a patch that implements it for the TS590S.
This rig is largely similar to the TS-590S but for some reason Kenwood
have changed most the EX command ids. Even though hamlib makes little
use of the EX command, it probably will need to for future
functionality implemenattion. Hence the new rig id.
Defects in the TS590s f/w can be addressed selectively according to
revision.
Enable kenwood_open function for TS590s.
For some reason the TS590s did not use the kenwood_open function, as
fetching the firmware revision may be required for this rig and it is
done in that function; it has been enabled.
