Here is how ACE communicates with ECS.

opening the DDE link:

    txtECSDDE.LinkTopic = "PGM->ECS|Any"
    txtECSDDE.LinkMode = 2 'manual dde link
    SendCommandToECS ("S,ace server") 'tell ecs what name to use to connect
to ACE
    SendCommandToECS ("C," & ECSClientID) 'tell ecs which DDE channel to use

The 3rd and 4th lines above are needed so ECS can send data back to ACE
(your program). You may not need them for what you are doing.  ECSClientID
is either A or B or C or D, depending on which of the 4 DDE channels you
want ECS to use.  The S and C commands are documented in ddecln.c in your
ECS folder.

Sending data:

    txtECSDDE.LinkItem = ecsmsg
    txtECSDDE.LinkRequest

You are executing the LinkRequest method before setting the LinkItem.  You
should reverse the order to be like mine.

You are also missing a comma in your I command.  You need 2 commas before
the SET, like this:

  Form1.Text1.LinkItem = "I,reminder,, SET, 0"

I also use "SET" instead of "set" in all of my commands to ECS.  But, I
don't know if case matters or not.  Case DOES MATTER in the item name.

Try both "0" and "False" and see which works (I think you have already done
this).

I hope this helps.
