Karin,
Jack makes a very valid point. If you are not using the K2 to PC
special cable to the AUX IO connector that removes all but TXD, RXD and
SIGNAL GROUND from the RS-232 cable, the K2 may display "strange
happenings" or in the worst case can cause damage to both the K2 and
serial port.
The auxbus is activated briefly on band changes to update transverters and the
KRC2, whether present or not. It’s possible that during auxbus activation, the
K2 may be missing an RS232 character or two. (Interrupts are locked out.) I’d
have to dig into the K2 code to determine this.

Please elaborate on exactly what you are trying to do and what you are seeing.
The AUXBUS data stream is not a part o the CAT system, and is used only
internally for
communications between our modules. If you are seeing CAT issues, then I
strongly
suspect something else is going on. One
Karin,
The AUXBUS is Elecraft proprietary and is used to communicate between
the MCU and all other firmware devices in the K2 system. So your
"Strange bit streams" are not likely to be related to WSPR controls.
If WSPR gets the proper data on the RS-232 signals, the KPA100 or KIO2
will
Hello Group:
I am trying to debug an issue I am having with CAT control of an Elecraft K2
using the WSPR software.
WSPR is setup to use CAT control for turning on the Xmtr. That part works
but I'm seeing some very
Strange bit streams on the AUXBUS during the WSPR control sequence.
I would rather
