[Elecraft] KXPA100 RS-232 problem

[David Orman]

The new beta firmware for the v2 ATU supports a configurable baud rate for
the loop controller. (Just released). I have a v2 ATU on the way but was
curious if you had tried the latest controller firmware located on Ciro
Mazzoni's website? It may resolve your issue if it was baud rate related.
Here's the release notes from the announcement:

New firmware release 3.17 BETA version for ATU 2.0

Changelog:
- baud rate setting in FULL AUTO MODE and SEMI AUTO MODE
- YAESU MODE 1: enables FULL and SEMI AUTO mode for YAESU transceiver with
a RS232 data port
- YAESU MODE 2: enables FULL and SEMI AUTO mode for YAESU transceiver with
a 8 pin data port (e.g. FT-857/FT-897)
- new ICOM CI-V addresses upgrading
