FR; command should retrieve current VFO (kenwood/kenwood.c:kenwood_get_vfo)
However, the kenwood protocol does not use 8 bits characters, which
is rather suspect. Anyway, it seems to receive something since it tries
to reply (certainly an error code, but with wrong speed?).

Maybe trying with some other known-to-work CAT program would help.
Easy to find under DOS/win32, not so easy under Linux...

This could be the most reasonable explanation. Have you tried playing
with speed/handshake/parity/number of data and stop bits/ etc. ?
Reading kenwood/ts870s.c, it looks like Hamlib is setting up the serial
port to 57600bps, 8N1, no parity.
Maybe the TS-870 cannot cope with too high speed?

Note: whatever speed value you setup the port, Hamlib reconfigures it.
So the TS-870 should be setup to 57600bps.

I'm afraid you won't have more luck since kontakt is based on Hamlib.
However, I'm almost sure Robert would be happy to have some feedback
on his development.

Please, let me know if the speed setup can help in solving your problem.
