Open/Close Serial Port

General
1

Hi all-

I'm wanting to use both node-red and another program to access a serial port, though not simultaneously. I was hoping to set up a dashboard button that I can use to open/close the port, but I'm not seeing a super easy way to do this. Was thinking that I might be able to use an exec node and have windows open a port instance, but this is a bit out of my comfort zone. Has anyone does this successfully, or have any ideas?

TIA!

Welcome j_gord

You need a Virtual Serial Port Emulator. After testing several programs, I chose to use Eterlogic VSPE.

Super helpful, thank you! Are you using an Exec node to interface with the Eterlogic VSPE, or something other configuration? Thanks!
