I put a ^M at the end of a string and sometimes at the beginning if I want to make the register is cleared before to new string is received.
^M ~ carriage return without the line feed.

Subject: [CRTech] XDS-Pro4r serial communication commands?
Has anyone had experience in sending serial commands from your automation?
I tried, port pid c ffd, but it does not change anything.
If I send that in putty software, I have to hit the return key.
What is the text for serial and line feed?
I think that is what is missing.
