[TRLog] TS-870 and TRlog

[Chris Adams]

Don,

There was discussion on serial port communication problems re: TS870
some time ago and I did some experments for Tree.  I had never had a
problem since I had used a straight though 9 wire shielded cable from
Radio Shack.  However, someone else was having problems...  so I built a
3 wire cable and duplicated the problem.  As far as I know, the 870 is
the only Kenwood that requires  rts/cts to be hooked up (and perhaps
they changed that on later models). Here is the conclusions that were
reached at the time...

So it seems that a 5 wire serial port with rts/cts works.
