Any small electronics Gurus here?

Here's how the serial stuff works.
The TXD RXD and Ground hook up to the Chrony with a 3.5mm stereo jack.

That same port uses a remote button that Grounds the TXD line which causes the chorny to step through readings that show on it's LED screen.

Grounding the TXD line while in Serial Control mode could damage things.
Thus why I want a way to keep that from happening.

I built a simple remote button. Gave it away.
I built several USB to Serial adapters. Gave them away.
Now I want to combine the 2 into one unit. So I can give them away.
I already have the USB to serial devices coming to put inside the chrony.
All the neat buttons are on the remote device anyway.

Way cheaper and should do fine. Even with a dual button this will work.
