I have a script written where I'm talking to a Serial port sending and receiving messages.

Is there a way send the string response to a tag created in the Tag Browser?

I have tried using the following:
Scope(\VTSDB, "Com3\R_Status", TRUE)
Scope(\VTSDB, "h{zfoiw%7k\5dhe8xmq^m", TRUE)

It does seem to work a bit but ends up crashing VTSCADA.
Also tried it with LocalScope.

Did you try this? Sorry, have to upload as a pic since typing it out created a smiley face emoji.

Have you tried the set function:

Scope(\VTSDB, "TagName").Set("Variable");

@mburns,

Please contact support to discuss the VTScada "crash" issue, the development team will want to find out what's happening.

Your question is unclear to me. Are you using a serial port tag or making a direct connection to the port, e.g. via ComPort()?

What is the tag that you want the response to go to?
