[Elecraft] KIO2, KPA100 - is SWR value available via RS232?

[ub5_073_oleg]

Thinking about remoting my K2 (currently QRP with KAT2, one
day with KPA100) via TCP/IP (e.g. with Ham Radio Deluxe), I
would like to know if SWR value is available via
- KIO2 serial interface?
- KPA100 built-in serial interface?

or do I need some external device like W1?

I am going to use an external non-automatic tuner, that's
why I need a monitoring of SWR - via PC because of remoting.
