[ICOM] Computer Interface Problem

[KE5CTY Bob]

I have an Icom 728 and am trying to do an interface to my computer.

It looks like (according to this link) that I only need to use my serial
cable for controlling the rig and for audio input and output.

Can someone confirm this for me?

Code may be taking a back seat for now,
but the pioneering spirit that put the code
there in the first place is out front of it all.
