Hi Bob,
To connect your radio to the computer you will need to add one more item to the mix.? You'll need either a TNC or? an external sound card device between the computer and radio.? You will also need the appropriate cables to connect things up.
I currently use a TNC for packet when I'm portable, but at the home station I use an external sound card with my VHF rig.
Two of the more popular sound card devices are the digirig and the SignaLink USB, but there are others.

Both digirig and Tigertronics (SignaLink) offer a variety of cables.? You can of course make up your own.
One benefit to using a sound card over a TNC is that you can run VARA FM.? Of course you will need to have a local RMS Gateway that has VARA FM available.
Ben, or one of the other Group members may have something they would like to add.
