[Elecraft] sharing K3 RS232 to CAT and Remoterig

You don't since you pass the computer connection through Bandmaster III
using the USB input when the output is connected to the K3 RS-232 jack.
You can not connect both the Bandmaster RS-232 connection *and* Remote
rig to the K3 RS-232 jack at the same time.

However, you can connect Bandmaster III to the K3 ACC jack and use the
BCD data (Yaesu) to indicate the selected band.  That will allow you to
connect *either* Remote Rig *or* the local computer to the K3 CAT jack.
Bandmaster will follow band selection from the rig whether you are using
Remote Rig or the local computer.

See the Bandmaster III manual and/or contact the manufacturer for
support.
