[Elecraft] K3: how to set up with CT 10 DOS?

[DOUGLAS ZWIEBEL]

OK...I admit it.  I have used computer logging since day one, but I
have never set up the rig to talk with the computer.

I need help!!  I am using CT 10 (DOS version).

I presume that I need to use the connector labeled RS232 on the K3 (yes/no)?
What baud rate is it?

On the computer...
I have an old machine running DOS (CT10).  It is a pentium 1.

I see two connectors on the back of the computer that are DB9s...same
as the K3.  They both have the same "symbol" above the connector, so I
am guessing that they are each the same.  Is that what I connect to?
Which one?

In the program CT, it asks me which COM port to put Radio 1 on.  How do I tell?

CT also wants me to set the baud rate.  Again, how do I know what baud
rate to use?

What else do I need to know?

Please reply directly to me at this email address.

Thanks!
