Hey,
Thanks for such swift reply.
Serial.flush() I put in just to try things out hoping it would help (Saw it on a website)
Are you familiar with NI (National Instruments) products?
I have used VISA test panel, in Measurement and Automation explorer (MAX) to send a character, that is in my switch case w, x, y, z and everything works fine.
However when I do the same in LabVIEW it does not, (Ps. I am not a novice to LabVIEW)
Please see attached Block Diagram and Front Panel
Kind Regards
Kev
