I have the following code: MSCommProj.CommPort = 6 MSCommProj.RThreshold = 1 MSCommProj.Settings = 19200,N,8,1

  • 0

I have the following code:

MSCommProj.CommPort = 6
MSCommProj.RThreshold = 1
MSCommProj.Settings = "19200,N,8,1"
MSCommProj.InputLen = 0
MSCommProj.PortOpen = True

And it opens just fine and connects but when i try sending the command:

MSCommProj.Output = "21 8901 5057 31 0A" & Chr$(13)

and

MSCommProj.Output = "21 89 01 50 57 31 0A" & Chr$(13)

and

MSCommProj.Output = "3F 89 01 50 57 0A" & Chr$(13)

as instructed by the user manual, it does not come on.

Here is the pages in the manual that shows this. Maybe i am just doing it wrong?:
