[Elecraft] Has anyone Interfaced a K3S and OM2500A

[charles at k5ua.com]

Having no success getting my Flex 6500 to interface with my OM2500A 
using ddutil and assorted null modems and serial to USB adapters.  Think 
of purchasing a K3S since it has a RS232 port that can interface 
directly to the OM2500A without the computer/USB adapter/ddutil stuff.  
Before making the jump, there are some questions I have about about the 
K3S/OM2500A combination:

1. Does anyone out there have a K3S successfully interfaced to a OM2500A 
amp using the RS232 post on the K3S?

2.  Since the K3S has up/down buttons for band changes, does the OM2500A 
reposition the load and tune stepper motors for each band on the way to 
the intended band.  In other words, on a rapid band change from 80m to 
10m, would the OM2500A reposition the tune and load stepper motors for 
40M then 30M, then 20M, then 17M, then 15M, then 12M, before 
repositioning the stepper motors for 10 meters?

3.  If the OM2500A does have to reposition the stepper motors for every 
band on the way to the intended band, is there some workaround using the 
K3S memories to go directly to the desired band without stepping through 
every band on the way to the desired band?

Thanks for the helkp,
