Baofeng PC / Remote Setup

Back Story

I currently do not have a "base" radio, but I do have several Baofeng radios. I decided to use my Baofeng UV-5RM as a base with an external antenna. The problem I encountered was holding the radio for communications, the quality of sound from the radio, and the antenna cable hanging from the radio. I thought if I could connect the radio to my PC so I could listen using my PC speakers, that would work a lot better for me. The only issue was that now I needed a way to key up and talk. I connected an AIOC adapter to the radio, but that eliminated me speaking directly into the radio. I was trying to figure out a way to accomplish this and with a cheap radio such as the Baofeng which is not mean for that kind of setup, I couldn't find a way to accomplish what I wanted.

I later purchased a Digirig, to setup my laptop with Winlink and VARA FM. After learning how to use Winlink, I realized the Digirig had the capabilities I was looking for to connect my Baofeng to my PC. I just had to figure out how to access the resources. The Baofeng was already connected to the PC for Winlink via the Digirig, and Winlink listens and transmits on the Baofeng, so how can I access this for what I want?
